BSOD after upgrading 7/8/10 to Windows 10 V1607 => 0xc000021a

Question: BSOD after upgrading 7/8/10 to Windows 10 V1607 => 0xc000021a

I am upgrading some machines, most go without a hitch but some have a mysterious BSOD.

I attached the dumps of a Windows 8 machine, i use MDT to upgrade to Windows 10 v1607 + do windows updates. BSOD happens after the first real boot (which means upgrade + updates have been done)

GHUM-L-E82PHJ12-Thu_11_24_2016_173811_42.zip

Already tried swapping the disk in a very simular machine (same model, different bios) but the problem follows the disk.

Anyone who can help me or point me in the right direction?

Preferred Solution: BSOD after upgrading 7/8/10 to Windows 10 V1607 => 0xc000021a

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hello and welcome to TenForums

The error seems to be related to a problem with the session manager initialisation.


Code:
WINLOGON_FATAL_ERROR (c000021a)
The Winlogon process terminated unexpectedly.
Arguments:

If you can boot into safe mode please try to run the system file checker and repair the system files. It might also be worth running a disk check with repair as well.

Greetings all,

I love your forums and been searching them for the last several hours. I've seen some great advice, however I haven't done anything due to the fact that all the situations seem different.

Here goes.

I booted up my comp this am and was greeted by the beloved BSOD... Windows Stop: 0xc000021a(0xc0000034) Error.

I cannot log on in Normal, SafeMode, Last Known good Configuration

I have an SP2 XP Pro Disc. I have access to the recovery console. I have done chkdsk. Alot of the posts have mentioned things like FIXBOOT or verifying I have certain files and etc. Anyone able to give me a hand getting this thing back up and running. One other piece of possibly relevant information. I ran a malware bytes scan on the comp. It found 1 error. I didn't pay attention to it, fixed it. Restarted and everything was good. 24 hours later, the BSOD came up.
Thanks

Greetings,

I receive a BSOD everytime I restart windows 8.1 or whenever windows restarts automatically to install updates (although it finishes updating successfully on reboot) with error code 0xc000021a. Besides that, the PC works normally. A few days ago the problem was reversed, i.e. Windows crashed on shut down with the same error but not on restart, this happened after I uncheched the Turn on fast startup option in power options which apparently solved similar problems for other people. I had to perform a Windows Refresh, keeping both files and installed apps intact, to reverse the PC in the previous condition so now it crashes again on restart but afterwards boots normally, though with some delay. I tracked the problem to Winlogon process terminating unexpectedly but I don't know how to fix the problem since a reinstallation of Windows didn't solve it. I suspect that a third party program is causing the problem and since I kept all of them after the refresh it still causes problems. Since I am not an expert however I could be totally wrong. The last incident happened today (18/02/2014) on restart due to a windows update. I would greatly appreciate any help offered on this matter.

Thank you

Hi I've been experiencing BSODs for the past week and was using Windows 8. As many system files was corrupted I thought it was causing by my faulty hard drive. So, I freshly installed Windows 8.1 Pro x64 on my PC. Then, I installed all required drivers, Avast! Free Antivirus, Comodo Firewall and some softwares. Now again I am getting occasional BSODs. Even sometimes when my computer becomes active from idle mode it automatically restarts and after reboot it shows information about last BSOD.

I checked minidumps with nirsoft's BlueScreenView and got that those BSODs are caused by the same ntoskrnl.exe error 0xc000021a. I am no expert when tackling BSODs. I would greatly appreciate any help offered on this matter.

Thank you.

had one last week that was a little different and it just magically disappeared (I'm building a new computer as soon as this semester ends if this computer will last that long).

I have MOST everything backed up on an external hard drive, but when i had tried to copy the my documents folder, it kept giving me an error, and I don't remember if I copied any of it over or not. The programs are all backed up, but AFAIK any documents I had are still on there, and I'd REALLY REALLY like to make a clean sweep through the computer and get as much copied over as possible.

It's windows xp home with SP3. It started after running an AVG scan overnight and the computer went on standby during the scan. My mom tried to wake the computer up and it froze and when i rebooted it (hit the power button once and it gave me the option to shut down, restart or go to standby like it would if i had gone to the start menu and done it) it gave me a BSOD (process1_initialization_failed), and i tried again and it gave me a different BSOD (the one im posting about).

I have a recovery console.ISO on a CD that I found off of these forums and it works, but I DO NOT have the windows XP CD. It's a Dell dimension 4600 (from late 2003 hehe).

I'd rather not have to wipe the HD or buy a new one because I don't want to spend money on this computer...If I can fix it with recovery console or by getting a windows cd from someone (if i can find one) that would be ideal.

Initially(in Oct2016), I used regback registry to fix USBPCap USB not working problem . After sometime It gave 0xc000021a BSOD . So i used Windows 10 iso to repair and maybe* messed it up with bootrec and bcdedit commands. Tried SFC and dism but no integrity voilations. I am able to boot PC ONLY by disabling driver signature enforcement(which stays till restart due to fastboot). I remember I had deleted some OEM*.inf before bootrec. Incidents may not be related. Minidump on debugging show ntkrnlmp.exe to be the problem. Please help. Even safe mode doesn't work. I don't want to reset since my PC is highly customized desktop environment.

If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
If errors show up and you see them a lot later, no problem, the errors don't affect the test.

Hi Everyone.
Hopefully I can resolve this... I've tried everything to sort this out but nothing so far has yielded any positive results.

I cannot boot my Win 10 Pro at all. All efforts result in the error C00021a. We can go into what I've done if you like (no problem with that) but for the moment, can anyone tell me how to do an inplace upgrade (Win 10 to Win 10)? I think this will probably sort it out since DISM is unable to do anything constructive. Problem is that I cannot do an "upgrade" as to do that you must be running Windows (normal boot) from the start otherwise Windows Setup throws up an error telling me to start the machine normally and run the upgrade from the external media. Is there any way to do this upgrade to bypass this error? I can't boot normally so it's impossible to fulfill this criteria.

I have a pile of specialised music programs on this machine. I really don't want to have to install everything again as I have them set up "just so". Hope someone can help.

I read the initial admin post about installing a program to help you guys with dump files - but I can't install that either as the machine won't boot into Windows. Of course, I've run the usual sfc scans and dism routines. Sfc won't run and repair - will only check. HDD scans come up ok. Dism routines will check (all comes up ok) but not restore health. Therefore I'm really at the refresh stage. I have boot media to do this but can't get any further...

Answer:BSOD 0xc000021a - Cannot boot Win 10 at all

Maybe this will help? https://www.reddit.com/r/techsupport...oot0xc000021a/ (4th post down).

Basically you boot the Windows 10 install disc then go to a Command Prompt.
Copy the existing C:\Windows\system32\config file to a a Backup folder.
Copy C:\Windows\system32\config\RegBack to C:\Windows\system32\config, replacing what's there.
Exit the install and do a normal boot and see if you are back to booting again.

If yes, would be a good idea to do a System Restore to a date before the problem started happening if you have System Restore enabled.

I kept my computer on over night and I accidentally hit the print screen button. I have a special program called 'Greenshot' so it overlays the screen with a grid region selector and lets you drag and save. I didn't drag and save so I left it like that over night.

As soon as I woke the computer up it froze the entire screen nothing could be down. Also a message pop up about failed nvidia drivers. I decided to just force reset my computer since their was nothing I could do.

Boot it up and got all the way to the logo and loading screen. A few seconds after I BSOD with the error 0xc000021a.

Reset the computer and the auto repair screen came up. I won't let me reinstall windows w/ keeping personal files, safe mode doesn't help nor does the force drivers option, I have no idea if windows have "Boot from last known boot" or have it verity all system64 files like windows 7. Nothing work in the repair menu but the command prompt which is label X Drive instead of C drive by default.

I heard windows 10 likes to secretly update bios so I don't know it that could be the problem. Anyways I have had boot loops in the past where if I plug too many usb devices in the back IO panel the computer will just boot loop.

Thankfully I have a secondary laptop to report my issues on. 
My problem is located on my Vizio all in One PC. Model is CA 27.  I am running windows 8.  Installed from windows store.
Using microsoft security essentials.  I do not have any other antivirus program or software installed.
 
I received notification that updates were available and ready for installation (I have the computer notifying me when windows updates are available for installation) - all other program updates are a notification only, I believe.
 
So, I hit the install updates and restart pc. Once the pc initiated the restart phase, the black screen with windows logo appears, with the spinning circle.  It then shoots to a blue screen with the following message:  Your PC ran into a problem restarting.  We are collecting information for you (then the percentage bar of information collection).  Below this notification is the following BSOD errorr number:  0xc000021a. 
It then loops to Preparing Automatic Repair, Diagnosing your PC, then sends me to Blue Screen of Automatic Repair:  Your PC did not start correctly.  Press restart to restart your PC, which can somtimes fix the problem.  You can also press advnaced option to try othe roptions to repair your PC.

I upgraded from W7 x64 pro to W10 x64 pro. Everything transferred the machine was up and running. I usually leave it running and let the power settings put it to sleep and turn it off. I noticed it was on and went to go look and see BSOD. Tried restart, debug, reset and save files, recover to last known recovery point and safe mode. Nothing works. I plugged the drive into my laptop to run checkdisk, defrag and make sure the disk works. Its an OCZ Vector Sata III 256GB. I discovered it needs firmware 3.0 but this still doesn't explain why it was workign just fine and when left untouched went to BSOD.

I downloaded the utility you provide but I gather it is taking the specs from my laptop and not the external OCZ drive that is plugged in. How can I go about getting the needed data over? And any suggestions for a fix.

Thank you,
LEIP

Hi,
My laptop on startup will BSOD (started last week), windows will repair and eventually, I can use F8 then F7 to boot.
Really appreciate the help in isolating what apps/drivers are causing this.

Thanks in advance!

I kept my computer on over night and I accidentally hit the print screen button. I have a special program called 'Greenshot' so it overlays the screen with a grid region selector and lets you drag and save. I didn't drag and save so I left it like that over night.

As soon as I woke the computer up it froze the entire screen nothing could be down. Also a message pop up about failed nvidia drivers. I decided to just force reset my computer since their was nothing I could do.

Boot it up and got all the way to the logo and loading screen. A few seconds after I BSOD with the error 0xc000021a.

Reset the computer and the auto repair screen came up. I won't let me reinstall windows w/ keeping personal files, safe mode doesn't help nor does the force drivers option, I have no idea if windows have "Boot from last known boot" or have it verity all system64 files like windows 7. Nothing work in the repair menu but the command prompt which is label X Drive instead of C drive by default.

I heard windows 10 likes to secretly update bios so I don't know it that could be the problem. Anyways I have had boot loops in the past where if I plug too many usb devices in the back IO panel the computer will just boot loop.

Hi Everyone.
Hopefully I can resolve this... I've tried everything to sort this out but nothing so far has yielded any positive results.

I cannot boot my Win 10 Pro at all. All efforts result in the error C00021a. We can go into what I've done if you like (no problem with that) but for the moment, can anyone tell me how to do an inplace upgrade (Win 10 to Win 10)? I think this will probably sort it out since DISM is unable to do anything constructive. Problem is that I cannot do an "upgrade" as to do that you must be running Windows (normal boot) from the start otherwise Windows Setup throws up an error telling me to start the machine normally and run the upgrade from the external media. Is there any way to do this upgrade to bypass this error? I can't boot normally so it's impossible to fulfill this criteria.

I have a pile of specialised music programs on this machine. I really don't want to have to install everything again as I have them set up "just so". Hope someone can help.

I read the initial admin post about installing a program to help you guys with dump files - but I can't install that either as the machine won't boot into Windows. Of course, I've run the usual sfc scans and dism routines. Sfc won't run and repair - will only check. HDD scans come up ok. Dism routines will check (all comes up ok) but not restore health. Therefore I'm really at the refresh stage. I have boot media to do this but can't get any further...

Can anyone help me ... Read more

I upgraded from Windows 7 to Windows 10 v1511; this works fine.  The latest version is v1607.  When I tried upgrading to v1607 I got severe problems, could not access the internet.  MS told me that my PC does not have the correct drivers for v1607 and MS assisted me to revert to v1511. Why has HP not supplied the correct drivers?  When do HP intend to do this?

I'm running Windows 10 v1607 as virtual machine under a Linux host in a laptop with 4GB memory. Before version 1607 w10 worked fine with 1GB memory, but now it wants minimum 2GB.

Is there a registry hack that will force w10 to run with only 1GB?

I've just started getting a lot of BSODs in Win 8.1. It started a day or so ago. I did install a second NIC for Hyper-V but I have removed that just to eliminate it from the equation.The crash is random, either away from the machine or working on it. Explorer crashes or hangs, ALL Browsers occasionally error and it'll just crash.
I am also getting errors such as:
error -5 from inflate: (null)
error decompressing shell32.dll
I have had various errors on blue scree noted below, once I reboot it appears okay for a time but is getting slowly worse.
The error on the blue screen is random:
BAD POOL HEADERs
KERNEL_DATA_INPAGE_ERROR
SYSTEM_SERVICE_EXCEPTION
0xC000021A
KERNEL_SECURITY_CHECK_FAILURE



I've run sfc /scannow. Initially this found a few problems that it couldn't fix which is related to "WRP found corrupt files but was unable to fix" I have also run in SAFE MODE same error.
I have also ran Dism /Online /Cleanup-Image /RestoreHealth, which gave me an RPC error and couldn't complete.
chkdsk /f finds no issues.
All Windows updates up-to-date as of today.
I have removed All MalwareBytes software.

Hello all, Im new here an need some help. I am trying to fix a friends Dell Dimension 8300. It was filled with tons of viruses. I got most of them, but after a restart I keep getting the BSOD error 0xC000021A followed by Cx0000034. I can't boot into any of the options when I press F8. I still get the message regardless. His CD drive doesn't work, so I cant boot from a disk. I removed the HD and put it in an enclosure and hooked it up to my computer to try and diagnose the problem from my computer. Is there anyone that can help me Can I replace files on his HD from my Windows XP Home Edition SP2 that will make it work again?? (He is running XP home SP2). I have not added any hardware or Ram. Just Windows live onecare to remove the viruses. Thanks in advance for whoever replies!

And yes, I have search all the knowledge bases and this forum and nothing has worked so far.
 

Answer:BSOD 0xC000021A Fatal Error

For anyone who has or will have the same problem. Here is what I did.

I opened up the tower for the Dell 8300 and took out the HD and the CD drive. (the CD drive didnt have the right drivers and can't find them, but it ran).

I plugged the IDE cable (master) into the CD drive and power cable.

Then I plugged the Slave end of the IDE cable into the HD.

Under settings (F2) I changed all the settings to "Auto" under the drive configuration settings. And changed the boot order to boot from the CD drive.

Then I inserted the Win XP CD into the drive, and rebooted.

Then I pressed "R" after the Win XP CD loaded all the files. The "R" is the repair Win XP installation. Everything loaded onto the HD without any data loss! The computer finally boots up now. Now I just have to put it back together LOL.

I would like to say I'm sorry in advance. I'm unable to use the required programs to neatly bundle and zip the crashlogs. This is my only computer in the house at the moment and I'm am only able to write this from a live usb of Unbutu I flashed at university. As the title suggests, I can't boot into my laptop to run the programs so I have no other means of presenting the info. I was only able to get the logs, again, by using the live USB and digging through the HDD. (It's not letting me install WINE either)

As for the actual problem itself, I have no idea what to do. It bluescreened randomly yesterday and never let me back on. It lets me on the automatic repair tool (which does nothing) and the command prompt. I ran chkdsk and memory dio and both came up clean. BIOS works no problem. I tried disabling signatures and it still crashes on restart. I honestly don't think it's a hardware problem at this point, but I could be wrong.

Any help would be appreciated. If there's more than just the minidump that needs to be included please tell me.

Thanks

Quick edit: These seem to be the dumps for the initial few bluescreens. If I recall correctly, it was a Kernal_inpage error that kicked off this whole mess. It seems to not be creating new dumps each time I get that weird hex-looking error (0xc000021a) each time I try to boot up. I can only tell by the filename, since it says December 1st on the dump and I've gone through more than a few bluescreens on the 2nd.

This morning, I needed to check my emails so tried booting up my laptop only for the BSOD saying "Your PC ran into a problem and needs to restart. We are just collecting some error info and then we will restart for you." I allow it to reach 100% but whenever it starts to restart my laptop just freezes. No matter how many times I boot my computer this always seem to happen which is why I am unable to follow the BSOD posting instructions. Is there anyway I can fix this as I need certain data that is on my hard drive?

Hi EightForums.
Just before Christmas I bought a brand new laptop, decided to get a nice new SSD to speed it up a bit, used the Asus tool Backtracker to switch the OS across to the new SSD. Now following that my laptop crashes either just after startup (with the BSOD 0xc000021a) or after a couple of hours of normal use. It seems to be happening every couple of times I turn my laptop on as well (for example after when it crashes, the next time it is on it definitely does not crash)(seems to be every couple of times I turn it on).
Really struggling to figure out what is causing it.
Also have noticed that my laptop screen is not turning off (even after half an hour of not touching it) but that could be totally unrelated.

I have a bootable USB with Windows 10, and another hard-drive plugged in running Windows 7. I have used the W7 boot to save my personal files which is lucky.

What I have tried:
- Boot to safe mode, disable driver signature
- Bootable USB -> "sfc /scannow /offbootdir=c:\ /offwindir=g:\windows" returns "Microsoft Resource Protection could not perform the requested operation"
- Registry replaced with backups

The SSD seems 'healthy'. Screenshot. CHKDSK passed but "failed to transfer log messages status 50". Are there logs I can locate manually on the troublesome drive and upload?

Hello everyone,

my friend has asked me to have a look at his HP "Envy" ultrabook running Windows 8, as it's stuck in a boot up "loop" whilst displaying an error code (0XC000021a)

I had a bit of shock, when I found out it doesn't have a DVD drive! Cue, several hours reading up how to install W8 boot DVD onto a USB drive. Thought I was making in-roads, but sadly not, as I can't use System Restore ("To use System Restore you must specify which Windows install to restore")

And I can't "refresh" the machine, as I get this message: "The drive where Windows is installed is locked. Unlock the drive and try again."

I just don't know what else I can do? Even tried running Hirens Boot CD from USB flash drive, but it doesn't even load!

Start the computer and immediately press the "Esc" key
This should give you the option to select the Recovery Manager
You can recover the system from there (if needed)

Another thing to try is contacting HP for a recovery USB drive. They're fairly cheap and good to have. Ordering instructions for the USA are here: Order Recovery Discs (USA) (the page is about a year old and I haven't checked the prices since then).

Ok. This is the furthest I've seen a computer go, and I don't have much hope left.

My brother has a laptop (~4 yrs old). The battery went bad a couple of years ago, and so it now need to be plugged in all of the time. The laptop was asleep when he unplugged it to move it, and when he opened the lid again, it had shut down (very likely because it died). Upon starting it, he got the BSOD and 0xc000021a error code.
The startup repair couldn't fix his problem. Two restore points he had on the system from installing DirectX a few days earlier didn't work. I tried entering safe mode, no luck. Now thinking I was at a last resort, I tried to refresh Windows, keeping his files but removing all the installed programs. I got a message at around 60% telling me Windows encountered a problem and couldn't complete the procedure. Same deal with the full reset. At this point, a reboot greeted me with "No operating system could be found".
I got a large USB and made it into a recovery drive, checking the box that said to include OS files or something (can't remember the exact wording). I tried again using startup repair, then reinstalling windows.

Shockingly, no luck. It failed once again.

A big thankyou in advance!

I recently bought a refurbished thinkpad (T420 i5 2540, SSD, 8gb ram, NVidia nvs 4200) with windows 7 professional. It worked fine at first, I could turn it on without a problem. However, as soon as windows updates installed, and I rebooted it, it refused to turn on. The power and Bluetooth lights would come on, then shut off after a few seconds. I unplugged, removed the battery, and pressed the power button a few times then held it, but that didn't help. After several attempts it finally boots, but BSODs as soon as it gets to "windows is starting". If I leave it for a long time (several hours) and try again, it often starts up normally. This whole process has happened many, many times over the last 3 days, with little difference each time. Launching startup repair just BSODs and it goes back to not turning on at all. System restore doesn't work, and I tried formatting the hard drive and going for a fresh install. It booted normally at first, but as soon as windows updates kicked in, it started failing to boot again. I was able to get a single crash dump (which should be attached). The bug check was 0xc000021a, on ntoskrnl.exe, at address ntoskrnl+72a40. I've tested SSD, ram, processor, etc., but they don't have any issues. I've never really had to deal with repeated BSODs before, so I have no idea what's going on.

Answer:BSOD on boot from clean install bug code 0xc000021a

In this case, it would be the best to go for another clean reinstall.

Because, from the description it appears to be a driver issue, a driver is conflicting during startup; and at the time the BSOD occurs, it does not have sufficient information to record the failing module in the dump.

Perform a clean reinstall exactly as suggested here: Clean Reinstall - Factory OEM Windows 7 .... hopefully it will solve this issue.

I threw the dump into the debugger, and it tells me, "Windows must now restart because the Remote Procedure Call (RPC) service terminated unexpectedly." This is bad for you because it means your dump doesn't have enough information to explain RPC's crash. Given the age and popularity of Win8, I'd suspect some third party driver / service is mucking things up.

Hi, I am getting a recurring BSOD. I have fairly recently installed a new, external drive and updated some drivers from the Gigabyte and Intel sites. The BSODs happen a few weeks apart, so trying to undo one driver update at a time, etc..., would take months/years to do. I realize I may have to fall back to that. However, I'd like to see if there are obvious signs from the minidumps or from anything else that could point to a specific driver or issue.

I've attached the BSOD zip file with the last 3 dumps, and I await further instructions.

Thanks in advance,

Where do I even start?
A client of mine came to me with their HP desktop and were saying it could not boot and restore points were not even working. I thought I would have this worked out in no time. I was wrong.

Here is the details for everything:
- Error code is 0X000021a and I can only see it when I, attempt to, boot into Safe Mode (Which all Safe Mode options do not work.)
- Normal booting into the OS results in a mainly blue screen with thin lines and streaks cutting through the screen and nothing is distinguishable.
- I tried System Restore and there is nothing there to access, says Windows.
In this next section, I run commands from the Command Prompt in the Windows Troubleshooting section of the boot.
- SFC scans result in this now: "Windows Resource Protection could not perform the requested operation."
- Chkdsk: Regular Read-Only mode tells me "No further Action is required" and running the extended commands, such as /f /r, takes a huge amount of time and I only did that once. No dice.
- DISM commands seem like such a good idea but I can run only one of them and it does not help me in any way. Say I run "DISM /Online /Cleanup-Image /CheckHealth" it gives me "Deployment Image Servicing and Management Tool. Version 10.0.14393.0.
Error: 50. DISM does not support servicing Windows PE with the /Online option."

is it possible downgrade from clean install of windows 10 v1709 to v1607 without loosing apps,files?
when i run v1607 setup it shows me this message:

Answer:downgrade from clean install of windows 10 v1709 to v1607?

Hi, the only way to do that is with the use of 3rd party software.
The most cost effective would be
a. Create a disk image of what you have
b. Clean install the new OS
c. Install the appropriate Easeus or Laplink product (one time cost)
d. Let the software 'install' your progs from the disk image.
These work well- I've had 96%+ success rate with Laplink with hundreds of programs installed. Good on configuration and settings too.

It's a question of your time to reinstall and configure vs money.

Note- from 1709 the next step back would be the CU at 1703.

Then if you install 1607 you would have to disable Windows Update - or with Pro you could defer the upgrade for a long time.

Note too had you followed our so often repeated recommendation to use disk imaging routinely, and you had an image of your system with 1607 installed, you could have restored that in under an hour.
E.g. Macrium Reflect (free).

3rd February 2017 UPDATE: End of servicing for Windows 10, version 1507 will now occur in May.​On November 29th, Windows 10 v1607 was declared the Current Branch for Business, also known as the Windows 10 Anniversary Update.

End of servicing for Windows 10, version 1507​With the availability of Windows 10 v1607, the grace period for Windows 10 RTM v1507 will begin. That means, after May 2017, Windows 10 v1507 will no longer be serviced, as only the two most Current Branch for Business (CBB) versions are actively serviced (ie, v1607 and v1511)

What this means for you? ​Basically, Windows 10 users on v1507 are advised to upgrade to Anniversary Update (v1607) before May 2017.

Hello,

I have an Asus U46E laptop (circa 2011) originally purchased with Windows 7 Ultimate 64Bit and problem free. It's since been upgraded to Windows 10 Pro 64Bit v.1607 and in all respects but one seems to be working fine. It won't launch from a rescue boot disk in the D: disk drive.

I researched as much as I could about this issue and the PC's System Information shows the BIOS Mode is Legacy and Secure Boot is Unsupported. My boot-up order shows device before HDD and every reboot confirms the disk drive is being accessed and spins the disk before moving on to the HDD. This issue apparently has something to do with Windows 10 UEFI and its Secure Boot feature, which also speeds up boot-ups.

I've tried every combination of boot-up keys, F2, F8, F10, F12, with and without shift+ and also tapping the F key or holding it down. Shift+ Restart F2 gets me into the UEFI Settings>Troubleshooting>Advanced>Startup Options> Restart but it still won't boot to the rescue disk or into any BIOS-like menu. It just continue to boo up the the HDD with Windows.

The bootable rescue disk which was accessible before updating from v1511 to v1607 was by Acronis. Now I've switched to Macrium Reflect and have created bootable rescue disks with WinPE v.10, v.5 and v.4 to see if the lagacy detail would help. None work.

I think the solution is to get into the BIOS (not sure if UEFI is BIOS) or the UEFI and turn off Secure Boot or Fast Boot but I don't see how or at least it's not follow... Read more

It appears that my recent update to W10 v1607 has screwed up my Logitech trackman (arguably the best mouse ever made, but stupidly discontinued by Logitech.) Every time I boot up or restart from Sleep, I have to press the trackman's reset button. Otherwise, there is no cursor. Furthermore, although I get the cursor working, if I stop using the mouse for a short time while typing text, the cursor freezes and I have to push the reset again to get things working. I believe that this malfunction is related to v1607 and has adversely effected other devices (eg, cams) as is now being reported in various forums. Any suggestions on how to handle this issue?

Until Microsoft fixes this issue, perhaps it would be best to roll back the 1607 update to the previous version of W10 that was on my computer? But, I'm a little shaky about doing this. Can it be done easily without causing further problems, and how?

Hey all, long-time lurker here. I wanted to start off by saying thank you, as I've found the info posted here (regarding other misc. problems I've had) to be very helpful

I'll start off with my specs:
Laptop: MSI GX640
CPU: Intel Core i5-430M

Video Card: ATI Radeon HD 5850 w/ 1 GB DDR5 VRAM

I don't know if any other information is necessary for this particular problem, but if there's any relevant info that I missed please do let me know.

Anyway, right now I have a problem with the above mentioned error. It first started while playing XCOM, and it pretty much happened every XCOM session thereafter, so I tried looking for some ways to DIY troubleshoot it. To that end, I've tried sfc, disk check, virus and malware scans, and also updating my drivers. All the scans didn't find anything unusual, and currently I'm pretty sure my drivers are up-to-date.

I want to add a couple of things here, just in the interest of providing as much info as possible, though I'm not sure if it will be pertinent. Anyway, for updating my drivers I used a third-party program called SlimDrivers, and I think it worked properly. I realize driver update software can be sketchy, but it had good reviews on cnet, which I suppose was as reputable a review source as I could find. But moving on, I goofed when updating my video card drivers, as I downloaded a version that, it turned out, was incompatible for my laptop.

Dear all,

I have this issue that has been driving me nuts ever since I upgraded my Windows 10 Pro x64 to v1607 (from 1507) recently. It's a desktop PC with a trusty old Logitech MX518 plugged into a back panel USB 2.0 slot. Same symptom with or without Logitech Gaming Software installed. Tried it with another (noname) mouse but same story. PC is free of malware, no sign of anything out of ordinary other than this. Needless to say that everything was working fine prior to update.



So what happens in the video is that when I click and hold an item and make a fast movement with the mouse, it loses focus of said object and drops it right there when it happens. This rendered drag&drop an infuriating trial and error process.

Another strange behavior I noticed is that 'shaking' a window will minimize another magically. What is happening?!

I'm not sure if the two symptoms are related to one another, I'd just like the mouse to work normal again, just as before the Anniversary Update. Is it because of some new mouse gesture or tablet oriented feature? I'm left puzzled here.

Thank you for any response, highly appreciated!

Hello,
This OptiPlex 3020 is encountering strange problem getting the Windows 10 v1607 or Anniversary update installed.  It looks fine in Update and Security as it finished initial install and prompt to "Restart".  The subsequent installation process after it's 1st reboot never get pass ...0%.  It is suggested that the latest OptiPlex drivers should be installed.  So I went to Support.Dell.com and allowed it to auto detect and install latest drivers and software.  Several Chipset update seems to have came down and installed without issue.  I didn't see any device drivers came down.  But the Windows 10 update still failed at "....0%" during the initial reboot.  According to Dell, OptiPlex 3020 is tested for Windows 10 v1607 Anniversary update.
1. Does anybody in this Forum know about this issue?
2. How else do I know if required drivers are installed?
Thank you and much appreciate your help.

Hi, i built my PC back in august and have had no issues, until now.
I got a windows update notification

-updates
"Cumulative Update for Windows 10 for x64-based Systems"
"Update for Windows 10 for x64-based Systems (KB3106932)"

as always i reset my PC when there's a windows update and when i do it cannot access the boot drive, so i proceed to go into the command prompt and input the "DISM /image:c:\ / cleanup-image /revertpendingactions" which puts me into the Deployment Image Servicing and Management tool

i move the pending.xml and pending.old
(via the "move C:\Windows\WinSxS\pending.xml C:\Windows\WinSxS\pending.old" command) the folders and it works until i restart my PC and it brings me back to the inaccessible boot drive window and i have to move the folders again.... is there a permanent fix for this? it's really annoying and i'm totally lost

So it all started last night when i accidentally tripped on my power cord, unplugging it from tthe tower during the login screen. At first, I thought nothing of it, and I just restarted the computer. But unfortunately I was met with the BSOD with that error code. All of the online solutions I have encountered that don't involve removing all my files or using a windows 8 installation disk I have tried.
So then after the BSOD I restart and get to a screen saying automatic repair failed. I try to refresh the PC- no luck. I'm definitely not resetting my PC and losing all my files so I go into advanced options. Foolishly I have no backup USB or anything so I try a system restore. Nothing happens, same old BSOD. Then I try the various command console solutions i found in the advanced settings command prompt.All of them don't work and give me a reply saying that the image was not found or "drwtsn32.exe" was not found in the image specified or whatever. It is always prefaced with "x:\windows\system32", not C:\. I cannot start in safe mode and disabling driver signature enforcement also didn't work. Any help before i just buy a windows 8 installation disk would be greatly appreciated.

As this is my first post, I did look for similar issues, but didn't find one.


I am by no means a computer expert, but have grown up around them, and have used them actively for the majority of my life, so I have a fair familiarity with them.

I recently completed my first PC build, and everything worked flawlessly. Windows 10 installed and ran fine, all my hardware was recognized without issue, and everything updated automatically upon startup. My goal was a strictly game-centric build, no overclocking or anything.

I come home today, and realize that my PC goes into the windows auto repair immediately, prompting me with an 0xc000021a error. My motherboard debug LCD was prompting me with b2 (short) 99 (short) a2 (long) my manual is very vague about it, but from what I have gleaned, it has to do with my peripherals, so I unplugged mouse and keyboard (supposedly 99 represents one or the other), no luck.

I initially tried to do a system reset, and it got to about 20% (both with and without saving personal files) and said that the process could not be completed, so I resorted to safe mode.I tried booting the computer in safe mode just to try to make some progress, and then upon rebooting to enter safe mode, it froze. I let it sit for several minutes before I manually reset the computer. Now it cycles between black screen, and MSI logo back and forth. I can enter BIOS, if I time it right.

Hi All..

I was reviewing my windows updates and saw two optional updates that were pending. First one was for MS office and it went through fine. Second one was some update to AMD vision control center. During that update screen flashed couple of times and went for re-start. After that I am unable to get into the system. I tried safe mode/debugging/low resolution mode etc.. But all resulted in the same blue screen with the 0xc000021a error message.

I am able to go only to command prompt. Nothing else (fortunately I am able to backup my photos by connecting external hard drive and using command prompt). I checked the SRT log file but it doesn't say any issue. All passed.

I tried refresh PC but it came back and said "There was a problem refreshing your PC. No changes made".

I tried using win ISO image bootable flash drive. It couldn't get through me in (I just tried with PC repair option when I booted with ISO image).

Is there a way I can get over it without re-installing?

Thanks in advance...

Answer:Windows 8.1 - Error 0XC000021A after optional updates

try.....
STEP 1: Enter cmd
STEP 2: Now in the Command prompt just type System Root\System32\Drwtsn32.exe -I?. This process will register the Dr.Watson as the default system debugger which has to be -> Press Enter.
STEP 3: Again type System Root\System32\Drwtsn32.exe and then in the window choose the option which are Append to existing log file, Create crash dump and Visual Notification.
STEP 4: After setting it up restart the computer by pressing F8 in the startup and select Last known good configuration.
STEP 5: Once it got booted up, again restart the system in the normal and now try to look at your optional updates to make sure not to install whatever may have broken it before.

If this does not work then you may have to reinstall.

Hi, today - after installing a firmware upgrade for windows10 on my surface 2 and a first successful reboot - I checked again for updates and found a new one that failed to install (didn't write down the error code, there was no specific explanation).
After a second shutdown I've got a 0xc00021a on reboot.
I don't have a backup or a restore point. I then followed the suggested steps to troubleshoot this error. I tried the "verify.exe" utility for drivers, which did not help.
I tried the Windows Settings "Troubleshoot" options: "Reboot" and "Safe mode with network", then I tried to "Disable driver signature enforcement" with no luck (same error).
Then I tried to reset the system from a Windows 10 USB installation, with the option "keep my files", but, surprisingly, I got the same error again and the process rolled back.
I really appreciate any help to solve this problem!

I have a g75vw Asus laptop which for the most part has worked fine. Late June the computer simply wouldn't boot into windows giving the error 0xc000021a next to the " " icon. This computer was originally using windows 7 but I upgraded soon after windows 8 was released in October. For about a week before the crashing, I had been using a ubuntu 12.04 live boot jump drive for learning python. It was after a linux boot that the computer crashed but I do not think the events are related. I had also installed connectify.me, a program that turns a laptops wi-fi adapter into a router which worked well for about a week before the crash. I have gone through all of the generic hoops including safe mode(s) system recovery using a usb flash drive, refresh, and the existent yet worthless self diagnosing tool. Microsoft was unable to help without a 100 dollar fee. 

Answer:Windows 8 doesn't boot. Error 0xc000021a

0xc000021a error usually means some issue with crucial system files, which could be actually caused by some bad hardware as well. I'd start with checking hard drive... Run hard drive diagnostics: http://www.bleepingcomputer.com/forums/topic28744.html/page__view__findpost__p__160520Make sure, you select tool, which is appropriate for the brand of your hard drive.Depending on the program, it'll create bootable floppy, or bootable CD.If downloaded file is of .iso type, use ImgBurn: http://www.imgburn.com/ to burn .iso file to a CD (select "Write image file to disc" option), and make the CD bootable.For Toshiba hard drives, see here: http://storage.toshiba.com/storage-services-support/warranty-support/software-utilities#diagnosticNote : If you do not know how to set your computer to boot from CD follow the steps here

I have a Windows 2000 Advanced Server system that is crashing on boot with a STOP 0xc000021a (abnormal winlogon or csrss exit) with exit status 0x00000080. It is on an Integrated xSeries Server in an iSeries 270, but I'm pretty sure that this is a Windows problem, not one with the host AS/400 system, because I was able to install a Windows system in a new image, and use it to look at the contents of the original image (AS/400 PC compatibility cards allow you to switch between multiple PC OS images). I checked the system logs for the original Windows system, and there were no messages relating to the crash. Dr. Watson was set as the debugger in the registry, but it doesn't appear to be saving a log or memory dump. No msgina replacement is installed. I bought the system used, and it was crashing like this when I got it, so I am not sure what change triggered this crash. How do I find out what is causing this crash so I can fix it?

Answer:Windows 2000 Advanced Server STOP 0xc000021a

You problem c000021a error is from winlogon.exe crashing.If none of these work, you might have to reinstall windows and use backups to restore the files.I1.) Download the UBCD 4 Windows and if you have access to another server with the same OS, copy the file winlogon.exe to a flash drive, the file is located under C:\WINNT\System32\winlogon.exe. Boot to the UBCD, It will ask you what you want to boot to, use your arrow keys on your keyboard to highlight Ultimate Boot CD 4 Windows, press enter, and it will load a windows XP interface. If it asks you any questions about starting drivers, network is unneeded, and is it askes you about USB, press yes. You will need to insert the flash drive, and, go to my computer. Locate the flash drive, and, copy the winlogon.exe from the flash drive to C:\WINNT\System32. It may ask you if you want to replace an existing file, press yes. Now, restart the server and boot from the hard drive. If this fixes your problem, your are in luck, if not, follow these instructions. 2.) If you use a backup program that makes a bootable disk for recovering data, and you backed up the entire hard drive, try to use that. If your winlogon.exe file was deleted, this could recover it. 3.) If you use the backup program that comes with windows, and, you backed up the entire hard drive, you can repair windows be booting to your Windows 2000 server disk, when the screen comes up with the options, about 5 minutes after booting from the disk, hit "R" on your keyboard f...

Today, I've been racking my brain trying to figure out how to recover from a problem with winlogon.exe which caused a "Windows logon process terminated" error with codes 0xc00021a and 0xc000034.

I found this article and it helped but didn't solve the problem. I thought I was faced with having to run a repair of the Windows installation, if not re-install.

That is until I decided to scan winlogon.exe using one of the online scanning services, like Jotti or Virus Total, to see if winlogon.exe had been infected. That's when I discovered the file was MISSING from \windows\system32. A Google search on a missing winlogon.exe file turned up this thread which provided the solution I needed!!!!

Many thanks to "coderitr" for your post! Copying winlogon.exe from \windows\servicepackfiles to \windows\system32 solved the problem beautifully!

Thanks!!!!!

I booted my backup PC with Windows 10 Preview on it after seeing the availability of build 10041 announced. The update was there along with a lot of other invalid updates. I boot up WIN10 at at least every other day to see what's new. So I was surprised see so many of these other updates. Many of them were for Intel HD 4600 graphics and ASUS Bluetooth hardware that would be imbedded on the MB. But my Win10 PC is AMD based and has AMD Radeon 3300 on-board graphics and no on-board Bluetooth. The strange thing is that those updates that cause the error are appropriate for my other main PC which is ASUS Z97-PRO and Intel i-469K based with Intel on-board HD4600 graphics... and ASUS on-board Bluetooth. It's spooky but it is as if windows update is confusing its search with my other Windows 7 PC. In WIN10 9926 Windows Update you can't decline an update that the system finds for you.

The system suddenly does a restart and then it can't find the C: drive. I have to power off the power supply for 10 sec and restart to get back to being able to see the SATA1 drive. I had to work through three cycles of those invalid updates and on the last I got the final 21a error code... after that on the next Win10 boot the build 10041 started to install normally.

I upgraded my RAM from 2 sticks of 2GB DDR3 1333 MHz to 4 sticks of 2GB 1333 MHz.
I purchased the exact same model number of the first 2 sticks I was using, went to BIOS and used the exact same settings for the 2 new sticks of RAM. The system runs but I get BSOD occassionally since then. I installed all the latest motherboard drivers, chipset, graphics card, and even updated my BIOS to the latest one but I'm still getting BSOD. Interestingly, I noticed that I get BSOD when opening some JPEG files (most still opens with no problem via Windows Photo Viewer), and I also get BSOD when simply exploring files in my computer (just Windows Explorer). So what I did was I changed my default photo viewer to the one that comes with Picasa. I already did the RAM isolation test, testing each ram in each of the 4 memory slots of my motherboard, and testing all possible combinations of 1, 2, 3 and 4 sticks and everything went well, the system boots up (but I didn't check if I will get BSOD when testing those combinations, I just merely checked if the system will boot up or not). I ran Memtest several times and found no errors. I ran the built-in Memory test of the motherboard BIOS and found no erros. I ran Windows Memory Diagnostics several times and found no errors.

Answer:HELP! 2 a day BSOD since upgrading to Windows 7 Pro

Try reinstalling windows, but use diskpart to zero the HDD before starting setup. You may be getting errors because of leftover data from your previous OS
boot from the dvd
hit shift + f10 at the "install now" screen and when the command window pops up type the following commands at each prompt
diskpart
list disk
sel disk 0 (or whichever HDD you want to install windows to)
clean all (this will take a long time
exit
then close the window and proceed with setup. It would also be a good idea to use the disk options menu to create a separate partition to store personal files and media.. about 100GB is more than adequate for windows and future programs. That way if the need arises you will have the ability to reinstall windows without losing anything except whatever you forgot to move to the other partition

Loaded symbol image file: MAudioFastTrackUltra.sys Image path: \SystemRoot\system32\DRIVERS\MAudioFastTrackUltra.sys

Please uninstall the M-Audio drivers completely from the system. Then download and install the Windows 8 version from the below link.

Hello!

I upgraded to Windows 10 a few days ago, and since then I have had BSODs. I had a few when I first built my PC, but not after that. I have tried using WhoCrashed to figure out the cause with no luck. I thought it was caused by Acronis True Image 2016, since at first I only experienced BSODs when it was backing up my computer. However, I found that not to be true. Even just a little while ago, I restarted my computer after a BSOD and left it on the sign-in screen, and it did three BSODs.

I have attached the .zip file from the Log Collector.

Thanks in advance for any help!

I upgraded my RAM from 2 sticks of 2GB DDR3 1333 MHz to 4 sticks of 2GB 1333 MHz.
I purchased the exact same model number of the first 2 sticks I was using, went to BIOS and used the exact same settings for the 2 new sticks of RAM. The system runs but I get BSOD occassionally since then. I installed all the latest motherboard drivers, chipset, graphics card, and even updated my BIOS to the latest one but I'm still getting BSOD. Interestingly, I noticed most of the time I get BSOD when opening some JPEG files downloaded from the internet (some opens with no problem via Windows Photo Viewer). So what I did was I opened the JPEG files using Paint then just saved it as JPEG files again and Windows Photo Viewer can open the files with no problem. I already did the RAM isolation test, testing each ram in each of the 4 memory slots of my motherboard, and testing all possible combinations of 1, 2, 3 and 4 sticks and everything went well, the system boots up (but I didn't check if I will get BSOD when testing those combinations, I just merely checked if the system will boot up or not). I ran Memtest several times and found no errors. I ran the built-in Memory test of the motherboard BIOS and found no erros. I ran Windows Memory Diagnostics several times and found no errors.

Though I don't have a dedicated cooler for the memory sticks, I have a lot, and I mean a LOT of fans in my casing... I don't have any application that monitors the temperature of the mem... Read more

Hello!

About a week ago I updated my computer to Windows 7 Ultimate. Since then, 90% of the time, when I boot up the computer a black screen appears on my screen and no desktop shows up. I can't do anything like get to to a task manager but the computer works fine in safe mode. Strangely, if I leave the computer for a couple of hours the black screen disappears and everything works perfectly.

Any help with fixing this problem would be hugely appreciated. Thank you

Answer:BSOD after upgrading to Windows 7 Ultimate

When does the black screen appear? After windows is starting animation, or after logon?
Has it a blinking cursor? (most of time top-left of screen)

Answer:BSOD critical_process_died after upgrading to windows 8.1

3 days old? I'd suggest returning it/exchanging it for a new system.

You can post the CBS log files in the Windows Update and Activation forum - I can't make any sense out of them.

I'll need the information from this link ( Blue Screen of Death (BSOD) Posting Instructions Please use Option 1 as it provides Event Viewer logs ) in order to get started on the BSOD issues.

Start by confirming that you have the best current driver for your network card. If that doesn?t resolve the issue, use the General Troubleshooting of STOP Messages checklist above

My BSOD is Kernel_Security_Check_Failure. It occurs after startup. It only began after upgrading to 10 on Friday. I never had crashes running 7.

Lately I've been making it through to the password screen and then the BSOD happens. Next time I startup, it might not happen.

I've updated all the device drivers, BIOS is up to date. I see critical on a lot of system drivers. I am not sure how to update or fix those.

Any help is appreciated.
