Upgrade RAM or downgrade operating system

Question: Upgrade RAM or downgrade operating system

I bought my daughter an Acer Aspire One D257 - despite the fact that it came with Windows 7, but only 1GB of RAM. I really wanted an XP machine, but it seems they no longer do them. I know that W7 Starter was supposed to be much more able to run in 1GB than full-up W7 - but I was still nervous.
Well, inevitably, the netbook hangs periodically - just becomes unresponsive for a few seconds. Given that it's pretty new, the only cause seems to me to be W7 thrashing around in too little memory.
So, what to do? I could upgrade the RAM to 2GB. It'll support that, and I've found a video of a guy doing it on YouTube. It doesn't look too painful - but I'm very nervous about pulling small PCs apart and putting them back together.
Alternatively, I could downgrade the netbook to XP. I'm well versed in installing XP - but the problem that occurs to me is the driver problem: if XP isn't supported on the machine, will I be able to identify and downlolad all the XP drivers I'll need? I've found a couple of very helpful sites, and I think it's do-able - although the sites refer to the slightly earlier model in the Acer Aspire range.
But before I take the plunge, I thought I'd ask the wizards of the forum what they'd do - or, in fact, if any of them has come across this problem before, and how they fixed it?
PS: a third option I'm thinking about is to dual boot the machine, which is easier to do when W7 is already installed than when XP is already installed. That way, unless I inadvertently turn the thing into a brick, even if the XP installation doesn't work, she'll still have the W7 installation to fall back on.

Preferred Solution: Upgrade RAM or downgrade operating system

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 (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Upgrade RAM or downgrade operating system

I have a HP Mini 210 that came with 1Gb RAM and Win 7 Starter. It was slow. I upgraded to 2Gb RAM and Win 7 Home Premium with the result that it is a delight to use. It will never be a speed machine but it is perfectly useable. Personally I would upgrade the RAM first, try again and if you are still unhappy then revert to XP. I would be interested to read what others have done.

Is it possible to downgrade the Operating System of Inspiron 3451 from Windows 8.1 to Windows 7?My mom is asking me to make this laptop to run a Windows 7 instead of Windows 8.1 as she is having difficulty in the new User Interface of Windows 8.1Is it possible?

Answer:Operating System Downgrade

Only Windows 8.1 Pro has Downgrade rights to Windows 7 Professional. Also you would need a Dell Branded Windows 7 Professional Reinstallation DVD to execute the Downgrade rights.
This system likely came with Windows 8.1 so no downgrade rights. However take the free upgrade to Windows 10 TH2 which has fixed most of the hassles with the Metro user interface of Windows 8.

I have purchased an 'off-lease' EliteBook 840 G1 which has come out of a corporate environment.The HDD was Encrypted, so all I could tell was the Notebook has an OEM 'Pro Windows 8' sticker on its base. I erased the entire HDD and re-installed a clean copy of the Win 8.1 OS. - all good and Windows Activated ok again as OEM The way I understand it from available literature, I then had two options:1. Upgrade to WIn 10 Pro (via electronic entitlement)2. Down-grade to Win 7 Pro (preferred option) I then 'down-graded' (clean-installed) the OS to Win 7 Pro. and Windows Activated successfully again as OEM. The system is running very well and updates etc. are coming through without issue. Could somebody please confirm I am not in breach of any OS upgrade/downgrade eligibility rights in doing this down-grade to Win 7. Thanks 

Answer:Operating System Downgrade eligibility

As long as it activated using the key embedded in BIOS you are fine.

Although Vista is said to be better and has more gimmicks related to tablet PCs, I really need to have Windows XP installed. So many programs I use work much better and faster with XP. (based test I made on clean installs on the same PC) And this is still just a tablet PC. So performance is an issue when compared with even a laptop for the same price. The only option I see when I customize my order is a XP restoration disk. Will I be able to wipe Vista with this and make a clean XP install? Why would I have to pay for both OSs? I don't want to waste disk space on a second OS and Vista won't work for me.  Moderator edit: Added clarification to Subject.

Why would I have to pay for both OSs? You have options to buy XP license from anywhere you want, not just by Lenovo. It will work just fine if you want to do clean install. For later question, it's obvious that you don't like the options Lenovo provided. So, you have 2 choices: add when you buy, or buy later =) anything extra is likely to cost you something.

Bought my laptop about 2 years ago. Came with Windows 8. Can't stand it. Bought a full install of Windows 7 recently, but after reading some posts here, am paranoid about even trying the downgrade. To make matters worse, my Windows 8 is in 64 bit, while the new Windows 7 I bought, is 32 bit. Has anyone had sucess with a simular situation such as mine? Thanks

Answer:Z580 Downgrade operating system?

Welcome to the forum ! I can't offer any advice on down grading the OS on your model, but COA key that came with your purchased version of Windows 7 can be used for either a 32 or 64 bit install.  Just download the appropriate 64 bit version of Windows 7 at Digital River and create a bootable DVD.  Here is a link to the Microsoft forum that will have additional links to Digital River......

This post is related to the laptop detailed above.

This is a new laptop, as yet unused, still in its original packaging. The laptop has installed Windows 8, which I would like to upgrade to Windows 10. This should be easy enough, as I've already performed the upgrade to Windows 10 on my desktop computer without any problem. However, before doing anything to this new machine, I'd also like to add a second operating system, Windows 7, to the same hard drive, and would be very grateful if anyone reading this post could explain, in very simple terms, how I would go about doing this. Ideally, I'd like to be able to choose which operating system to use each time I start the laptop. Please include as much detail in your reply, with step by step guide.

I am running an old computer with ME. I am going to get XP. However there appears to be an upgrade version of XP and the whole XP operating system. I assume that the upgrade option will be easier to install. Which is the best and easiest option?.Any comments gratefully received

Answer:How to upgrade from ME operating system to XP

If you want to keep all your old programs and settings, go for the upgrade.If you want to start afresh with a clean installation of XP, nothing saved, go for an oem or retail copy of XP. You can always burn your old data to cd\dvd.Make sure your ME computer has enough grunt to run XP. A 1ghz cpu and 512Mb of ram is a good starting point.

Hello, I'm looking for some advice please as my computer is broke and I'm stuck without it.
Last weekend it just stopped working, I used it in the morning with no problems then in the afternoon I turned it on and it wouldn't start up, long story short is I ended calling Dell and they have told me that my computer has automatically upgraded to Windows 10 but my Dell XPS 7100 isn't compatible with it, now I have no operating system at all!
I paid them £119 for a years support and another £30 for a Windows 7 ultimate disc which they say I'll receive tomorrow (Friday)
I use my computer for work as I'm self employed and need to prepare quotes and invoices etc for my customers, I've been all week without it now and am fuming that this has happened, I didn't even want Windows 10, why would it upgrade automatically? It's cost me a lot of time and has now cost me money and I don't even know if all my files will be there when it's working again.
Just thought to vent on here and see if anyone has any advice, I'm also not happy that I've had to pay for Windows 7 ultimate again as I already bought it once with my computer but it seems it was preloaded so I didn't get a disc which I now need to reinstall, Dell support said they will assist with the reinstall and then block Windows 10 from trying to do this again! Great now I feel under attack from the Windows 10 upgrade :-/

Answer:Windows 10 upgrade has deleted my operating system

Run your W7 disc and you will probably loose everything on your computer. I would wait and see what information that you get on here first.
In the meantime does your computer try to start or is it just dead.

Helping a friend on his Acer Aspire V5 laptop that was running an OEM Windows 8 to upgrade to 8.1.

After selecting the Upgrade to Windows 8.1 via the store, the system went through it's install procedure, however after it does an auto reboot, it gives you a blank screen with the message No Operating System found, in the upper left corner.

But, you can turn the machine off and back on, and it will boot just fine. However if you select restart it does the same thing "no operating system found", on restart and again you must power down and power back on.

I have searched for fixes, but all seem to point to some sort of re-install process. I am not to crazy about the idea of re-installing to factory settings or doing a repair back to Windows 8 and attempting to upgrade again, are their any known shorter fixes for this?

And if I do go back to Windows 8, and try to upgrade again, what is to say it won't happen again?

I recently upgraded my system's graphics card and processor to an FX 6300 with an R7 250X. I had some issues with my old OS, so I upgraded to Windows 8.1 Pro.

After these upgrades, I'm now getting various different BSOD's (Blue screen of death) upon boot and while using the machine. For example, NTFS_FileSystem_Error, Kernel_security_check_failure and several more which I cannot remember off the top of my head.

In addition to that, I get error messages on start-up for various different programs, sometimes Google Chrome fails to launch, and I'm unable to use any of the Windows Metro apps - they simply launch and then crash.
Iv'e got all the latest drivers, I've ran an HHD check within windows, and a RAM test using memtest86 and nothing abnormal was found. I can play games when I'm not getting BSOD's at solid FPS, which shows me that all of my new hardware is not at fault.
It's getting to the stage where I'm considering downgrading to Windows 7 again.

I'd appreciate any help that I can get on this. Thanks in advance. I can post anything else that would help you guys out with troubleshooting.

Answer:BSOD after hardware upgrade and operating system reload

When you say to reloaded Windows 7, does that mean you re-booted Windows or re-installed Windows.If you reinstalled Windows 7 it was completely unnecessary for a RAM upgrade, Windows would have picked up the extra RAM without any intervention from you.The first thing to do is check them memory is properly seated and is compatible with you motherboard.

I'm new here so pardon if there is any mistakes.

Anyhow I am currently using windows 7 (not a fan of windows 8). Since windows 10 is released I wanted to install and try it.
Initially I installed windows 8.1 in my D:\ drive (works normally as far as I can tell), and upgrade it to windows 10. I am keeping my windows 7 in drive C: as I do not have any other working computer if the installation failed.

So halfway upgrading from windows 8.1 to windows 10, the upgrade failed and a restart is needed. When restarting I tried to reset the installation but even that is failed. When restarted again there is no operating system in that drive (drive D: ) ??

Currently I tried to reformat my drive D: (windows 10) with my current windows 7 (installed in drive C) but it says the volume is in use by another process but it refused.
Drive C: - windows 7, still functioning properly
Drive D - where windows 8.1 is located and upgraded to windows 10 but failed, currently cannot detect any os when i boot from drive D: , and cant format the drive.

I know its really stupid and complicated the way i installed my windows 8.1 with my windows 7 intact, but I'm worried if the installation failed, I have no backup computer to fall back. Is there any suggestions that I can do?

Answer:Windows 10 crashed during Upgrade. Unable to detect operating system.

Try booting Windows 7 to Safe Mode (F8) then see if you can format D: from there. Do a quick format, full format is not needed.

Hey all! I am pretty new to this kind of Win7 issues, so I hope some of you will be able to help. Story goes...

After few hours of gaming the computer died. (It happened right after switching keyboards.) Now, on every setup BIOS(?) comes up with list of options (F2 enter BIOS, F11 boot options, F6 Flash etc.). After that a black screen with error message comes up: Missing Operating System.

I tried rebooting from USB (since I have no disk-drive) and I keep on getting the answer: Error Loading Operating System.

Any ideas?


Answer:Missing Operating System/Error Loading Operating System

All unlikely, but possible - (a) your HDD died. (b) your bios became corrupted (c) your HDD boot sector became corrupted (d) your HDD partition is corrupted.

Does the drive spin up when you switch on (feel it)?
Check the bios to see if the HDD is reported correctly and is at the top of the boot order.
Find a bootable CD - an OS installer, or create Easeus partition manager bootable CD and boot from it. What does the HDD look like with Easueus?

First of all sry for my english.

I had a crappy computer with 1.8 dual core and a crappy graphic card. So I bought a new one with the following.

AMD Athlon II X3 435 2.9GHz
4GB DDR3, 2st DIMM-platser (memory)
ATI Radeon HD5450 1GB (graphic)
and windows 7

The thing is I am playing a game called hon and my old computer made it fine with just about everything on max. And with my new I cant even move or pretty much anything. I have updated the graphic card and I am sure its nothing to do with my internet connection.

Thank you.

I wanted to speed up my system (I play a lot of games) so I made some changes to my system. I had a:

- PII 300
- Voodoo 3000 agp video card
- 6.4mg primary
- 500mg slave
- Win 95

I figured that I was probably bottlenecking with my processor, so I went to the computer store where they recommended that I go to an AMD K-6 550. The guy said that I should see about a 70% improvement in opening programs. In addition, I got the Win 98 upgrade which I needed in order to run the chip.

After having those changes made, it doesn't run any faster at all. So my question is:

1. Is the AMD chip truly faster than my previous PII?

2. Is there something else that could be slowing my system down?

The technician mentioned that depending on how my drives were set up, the slave may be slowing things down a lot because it's old.
Any thoughts anybody? I don't want to spend another dime until I know that I'll see results.

Hey, I just upgraded my powersupply, from a 350Watt system, to a 400Watt system. I also increased my RAM from 512pc3200, to 1 Gig of Pc3200, and added a few fans. However when I started up games like Counter-Strike:Source, my frames dropped from about 50-80 average, to 10-30 average, even when I'm standstill.

I also tried out Aquamark3 to double check that it wasnt just source, and when i used to get 50-70k, now i get 10-20k scores.

I installed everything correctly, and double checked. When i put the ram in, I made sure all of my components were placed back. My power connections are all accounted for and I'm running my OS fine, its just when there is any intense graphical processing is when I run into trouble. I also clean uninstalled my drivers, and re-installed them but with no luck.

The only problem I can see is that i have two different manufactures of RAM running in my comp. However i dont think this is the case because both sticks of ram are compatible with my motherboard, and both are pc3200 DDR RAM, 512.


MB: P4P800 Delux W/800mghz FSB
CPU: P4 2.4 w/Hyperthreading
RAM: 1 Gig Pc3200

Has this happend to anyone, or does anyone have any suggestions? Im kinda stuck in the mud and i've run out of options.

I am still running windows media center on my 8.1 desktop and am looking for an eventual replacement. Could I upgrade to Windows 10 now in order to secure the free update, then go ahead and downgrade back to 8.1 so I could continue with WMC until it officially dies?
Would this allow me to have an upgrade to 10 whenever i decide to finally drop Media Center?

I recently picked up a a7v400 MX motherboard and a athlon xp 3000 cpu (333fsb). After installing them, however, I discovered that my processor is running at 1300mhz... instead of 2.167!!! My 512 stick of pc 2700 isnt run up to its normal 333 speed either.

My CPU reads as an athlon XP.

Question: upgrade/downgrade

im currently using windows 98 which came with my computer, so i dont have the discs or anything. my question is if i upgrade to windows xp:

1) will my documents, music downloads, etc. be lost?
2) can i downgrade back to windows 98 (w/o the disc) and have it basically be the same as before? ie with all the same programs? if so HOW?

please post answers or email me at [email protected]

thanks a lot


Hello and welcome to TSG!

If you want to know if your computer is compatible with Windows XP Home, take a look at Windows XP Home Upgrade Advisor.

If you do not have the Windows 98 installation disk, then you cannot go backwards because you would need it to install the operating system.

Answer:T61 Windows Upgrade After Downgrade to XP Pro

You can't believe what the "Sticker" says as my T61 came loaded with XP Pro as well and has a Vista Basic sticker on the palm rest. However, a full set (4 DVD's) of upgrade discs for Vista Business came with the Notebook. You will have to contact Lenovo to get an upgrade set of Vista discs if you wish to have Vista. I guess it's a personal thing, but I can't see the point, at this point, in "upgrading" just to get a few bells and whistles and eye candy. Cheers Malai5

Hello Friends,

I upgraded my Lenovo Ideapad Z 570 to Windows 8 a couple of days back. But the new OS is a pain. it has slowed down my system substantially and also some reference memory......terminated kind of errors are also displayed frequently. may b this is coz i did not do any BIOS upgrade before switching to Win 8. Was i supposed to? Tried calling the customer support and they asked me to contact microsoft about the problem.

Whatever..what i want now is to go back to my previous win 7 and would appreciate if you people would guide me. i saw a discussion on the same topic in the forum for an acer pc, so would be glad if you help me out as well.

I have never run any backup or anything. data is not much important anyway.just some movies etc.
i have the win key on my laptop, but there's no cd.

Pl help.

PS: Located in India..if that makes any difference to the kind of updates available.

Answer:How to downgrade lenovo pc to Win 7 after upgrade to Win 8??

Hello ankitkr and welcome to Seven Forums.

Couple of questions. When you upgraded did you do a clean install (format the entire hard drive), clean install (format only the C: partition containing windows 7), or something else like dual boot? Do you know if your Lenovo still has a hidden recovery partition containing the original Windows 7 and other factory installed software? A screenshot of your Disk Management would be helpful to see how your hard drive is configured and what you have to work with.

Answer:downgrade from xp pro to xp home with upgrade cd. please help!!!

To use this CD you will need to first most likely erace the drive using a program like Killdisk.

Then you will need to have either a Windows 98 (I think), 98se, 2000, or ME full install CD handy. Sometimes recovery CDs won't work. Without one of these CDs you cannot install the upgrade.

During install it will ask you to insert the old CD from above and will check it to make sure you are eligable. Then you can install as usual.

I don't see why you don't just stay with Pro, though.

Hi there,

Hoping someone can solve this mystery for me. Just "upgraded" my computer, but the performance is way below par and games (e.g., "Portal") that used to load in <10sec simply... don't. Here's what I upgraded:

AMD Athlon64 3200+


AMD Athlon 64 X2 4800+
2GB (DDR2)

and I brought my 120 + 160GB HDDs, and Asus EAX1950Pro over to the new board. Also relevant is I'm running XPPro SP2 with all software updates applied (I did a clean install on my OS partition).

My symptoms:
- In Task Manager, I haven't seen CPU usage drop below 44%. When idling, the first core hovers between 0 and 40% and the second core shows a virtually constant 85-95%. This has persisted since the first time booting Windows, with virtually no background tasks.
- When the system actually does some work, the first core kicks in and the second drops down. That is, peaks in core 1 correspond to valleys in the core 2 graph. Never below around 50% though.
- The game I've been trying to get running, just to make sure everything is working, is Portal. Relatively small but high system requirements, but should be fine because it ran on my old system, right? No. I get to the loading screen and it just sits there. When I tap the Win key to try and get it to minimize, it doesn't, but I can tell the Start menu is working because if I move the mouse to where it "should" be, it changes to the regular arrow. I...

Answer:Upgrade feels like a downgrade

first thing i don't recomend using a registry cleaner. it is ok but sometimes you don't know what you are deleting. you said you have upgraded and then reinstalled windows. if this is the case i think you will need to upgrade all you driver. if you use a program called performance test that cna be downloaded for 30 day trial. do a scan of you system with that and it will tell you the pc's performance then go and upgrade driver and then see the number increase.

try disk clean up. click start run then type "cleanmgr.exe"

try disk defragmentor- start run type "dfrg.msc"

those are some recommendation as well as unchecking the program that start up. you say the processes are running high which ones in particular and as well have you fone virus scans or spyware etc.

Hi guys,I recently purchased an acer aspire 751 netbook, with 2GB RAM, 250GB HD . It came with vista preinstalled. I'm not sure what the processor is, but I think it's a bog-standard netbook processor, nothing special. Anyway, the thing is an absolute nightmare because it is SO VERY SLOW. I suspect vista to be the main problem (and maybe some of the preinstalled virus software etc, but mostly vista...). Some people have told me to upgrade to Win 7, others have said that going to XP is a better idea.

I was running 8.1 Pro on a cheap Acer box (i3 + 8gb ddr3 + 512gb SSD) as Administrator. I had forgotten that once upon a time I had the machine hooked up to a TV --which means that I had created a user "TV User" probably with the password in the "hint" or "forgot password" box on 8.1 because it was being used as a public/open to the family/friends machine.

So when I upgraded from 8.1 to 10 it locked/disabled the Administrator account (which I know the password for) and it enabled this "TV User" account which I DO NOT know the password for.

I tried all the usuals... booted to install/ISO and tried to repair... error could not repair. Tried to revert back to 8.1... error with partition, could not revert. Tried to "reset" or wipe the box... error with partition. Booted with the install ISO and tried to activate the administrator account via command line (net user administrator /active:yes) but as soon as the machine reboots the administrator account is back hidden.

I don't really care about the machine. I can reinstall very easily. What I am concerned about is the licensing for 10. I have a legit 8.1 license but I think that means I'll miss out on my "free upgrade" if I put 8.1 back on it... and I do not have a 10 license nor do I want to pay for one.

Why would you miss out on the free upgrade? Reinstall Windows 8.1 make sure it is activated. Make sure you have an administrator account created and that you can log into other than the built in "Administrator" account. Then upgrade to Windows 10 using the Media Creation Tool - no need to even run any updates for Windows 8.1 beforehand.

The hard drive is dectected in the BIOS, as is the CD Rom and floppy drive. It properly recognizes the amount of RAM.

Hi all,

I just bought a Lenovo X140e, which comes with Windows 7 Professional preinstalled through downgrade rights from Windows 8 Pro. I setup the computer fine under W7, then proceeded to install W10 so I could get the "hardware license" for Windows 10. At the moment, I don't want W10 on this laptop.

After activating Windows 10 on it, and making sure the license is activated, I installed an SSD on the laptop, however now I cannot activate Windows 7. I downloaded a W7 Professional ISO and put it on a USB using Rufus. The install goes okay, but Windows 7 is now asking me for a license key. Where is it? The bottom of my laptop only has a Windows 8 Pro sticker, there's no product key sticker.

Thinking it might be bad ram, i removed the ram, and reset it back to the old configuration, with the same result. removed all components, removed cmos battery, let it sit, resinstalled one at a time, and it booted fine. Now it is back to the same thing, will not post at all. I am going to remove everything, and remove the mobo, and try to boot it with the mobo out of the case next, ive read some of the threads here on the forum, and have tried most of them already... Just find it hard to believe that the mobo may have died right then, but thats what im leaning towards... Any ideas?

Answer:Computer will not post after upgrade, downgrade?

It is possible that the motherboard was damaged by static or a bad RAM module

Hi all,

I just bought a Lenovo X140e, which comes with Windows 7 Professional preinstalled through downgrade rights from Windows 8 Pro. I setup the computer fine under W7, then proceeded to install W10 so I could get the "hardware license" for Windows 10. At the moment, I don't want W10 on this laptop.

After activating Windows 10 on it, and making sure the license is activated, I installed an SSD on the laptop, however now I cannot activate Windows 7. I downloaded a W7 Professional ISO and put it on a USB using Rufus. The install goes okay, but Windows 7 is now asking me for a license key. Where is it? The bottom of my laptop only has a Windows 8 Pro sticker, there's no product key sticker.

Please help! How do I find my Windows 7 key?

Answer:Please help. W7 activation issue after downgrade and SSD upgrade

I don't know if this will give you the key you need but it's probably your best option at finding it,

I don't post often, but I do read a lot, and there is a lot of good info here. Background: I am running a dual boot Win XP (32 bit) and Win 7 RC 7100 (32 bit). I have the Digital River WIN Pro Upgrade (32 bit). I have read the UNAWAVE downgrade scenario from Ultimate to Pro and the WIN XP to WIN 7 PRO upgrade here.
I am debating which OS to change. I really like the RC version and have been using it for quite a while. But since it is my main OS, I would hate to screw it up doing the downgrade as suggested by UNAWAVE.
If I upgrade the WIN XP OS, I am not sure If I would still be able to dual boot between WIN 7 RC and WIN 7 Pro.
If I do upgrade XP to PRO, would I be able to use WET to transfer my settings from RC to PRO. I am leaning towards the downgrade option, but wanted some more input from the "experts".
Any suggestions would be appreciated.

Answer:Upgrade WIN XP or Downgrade 7 RC build 7100

Your RC version will start expiring in March 2010, so now would be a good time to make a decision what to do about your programs, files, & settings.

Recently got an e6430 with bios a A13. I wanted to downgrade to A12. Every time I do it, the process does the same thing. It has a progress bar saying it's preparing to update, but then just reboots and nothing changes. I've used DOS bootable USB, and Windows methods, neither is updating the bios. 
I tried going to A03. Tried to going A18, A20, etc. But nothing ever works. The progress bar says it's preparing, then reboots.
Is there some setting I'm missing? I don't see some sort of "allow downgrade bios" option in the bios settings list.

I have a toshiba Satellite c855d-s5100, which I bought a few years back and came with windows 8 loaded. I upgraded to win 8.1 (which I loved over all), and then recently upgraded to win 10. Well, I thought I had done my research before upgrading, but I must have had a dyslexic moment, because while there are at least 50 Satellite models that are considered "suitable" for 10 by Toshiba, mine isn't one of them.

I had been holding out , hoping that the horrible lag and freezes, as well as the other more minor glitches, would soon be worked out via driver or OS updates, but eventually I gave up and decided I wanted to go back to 8.1. This was on Saturday, 34 days after install--which is when I found out about the 30-day easy reversion back to your previous OS. Heh.

EaseUS does me no good, since you need to have the program and create your back up before installation of win 10. Granted, had I access to more money, I would have gotten a memory stick and backed up 8.1 like an intelligent person; patience and I would have set up a recovery partition. But I didn't--and for the first time, I can't figure out how to fix my oops.

I opted to reset windows once I realized reversion wasn't going to happen easily, and I hoped that maybe the reset would help some of the glitchiness.


Well, unlike when I reset 8.1--where I was kicked back to 8, all of the bloatware that came with my computer returned, etc., this time I had NOTHING. Realtek was my audio con... Read more

Hi there,

I'm sorting out a Christmas present to my step dad who has been very good to me this year and i'm running up against some problems.

He has a windows vista PC that is causing him no end of problems. Viruses everywhere, problems with certain functions etc so i said i'd sit down over christmas and completely wipe everything for him and start again.

I'm going to back up everything onto my external HDD. I will scan the contents with malwarebytes and AVG. Will this be good enough to make sure i'm not reinfecting his machine with his personal files?

The next step is to reformat the drive and delete everything. This should get rid of any virus i hope. Unless there is something in the master boot record right? Is there a way I can check this?

Finally my last question is which OS to put on the system?

Vista is pretty terrible i think and would be the last resort
XP is great and i have a Boot CD for my laptop that i can use. Would this be possible?
windows 7 could work but as a pretty poor student i cant afford the ?70 price tag. But i might be able to get hold of a copy form someone although again i'm not sure if this will work. Dont really want to use an illegal OS as im sure the downsides are pretty big like no windows updates.
So to summarise:
1)will AVG and malwarebytes make sure his personal files arent infected?
2)how can i check the MBR is virus free?
3)which windows would be best to reinstall?

Thanks for all your help,


Answer:Windows vista upgrade to 7 or downgrade to XP?

If you format, you don't have to worry about MBR.Vista is pretty terribleOn infected computer, any OS will be terrible.Dont really want to use an illegal OSNo, you don't.There is no reason for going back to XP, 2 years old operating system.If you can't afford buying Windows 7, formatting and reinstalling Vista will do just fine.will AVG and malwarebytes make sure his personal files arent infected?No security program will do, if the user doesn't play responsibly.

I have Tecra A10 with pre-loaded Vista Business. I completed the installation.
There are two things I would like to know:

1. If I downgrade to XP Professional by using Product Recovery disc supplied together with the notebook should there be Toshiba utilities and drivers as well or I need to download them manually?

2. Right now I do not have to activate my Vista, but in case of the downgrade to XP and, possible later upgrade to Vista again by using Recovery DVDs I made, will I have to undergo activation procedure?


Answer:Downgrade/Upgrade to XP or Vista - Tecra A10

1) The Toshiba disk (with Win XP???) contains always the image files. A image is a package which contains Windows OS, drivers, tools and additional software. After the installation from the recovery disk it?s not necessary to install any drivers.

2) You can activate the Vista and then can create an image.
This image will contain the activated Vista. So a second activation will be not necessary.

I downgraded a laptop from Vista Home Premium to XP PRO because I have an upgrade of Windows 7 Pro that would not update from the Vista OS.

The computer is a Compaq CQ60 and I ran the Windows 7 upgrade advisor and it said that it was compatible with everything, except it said that it needs more memory. (It is showing 1.8 GB installed, which I am assuming the remaining memory is being used in shared video)

I am planning on updating the memory to 4 GB anyway so it should be fine.

However, I have my boot order set to DVD first and moved the HDD all the way to the last boot item. When I restart the computer with the DVD in, it goes right past it (I can hear the DVD spin up, but then nothing happens) and then boots to XP. If I try to run the setup from the DVD it says that my version of windows is not upgradeable.

Any ideas?

Answer:Downgrade of Vista Home to XP to upgrade to Win 7 Pro

you cannot upgrade from winxp, you have to do a full install. running from setup is only for upgrading.

put the wiin7 dvd into the drive and reboot the system. As soon as it powers on, start tapping the space bar.

I'm going to be looking into options to upgrade or downgrade for this laptop due to Vista's general slowness compared to other Windows operating systems.

They have Vista Home Premium SP2 but are looking at changing the operating system. Now that Windows 7 is out I'm looking into a few options. Have decided to leave the existing system alone and remove the original HDD while testing - this I will definitely do as I can't afford errors on an upgrade in case something goes wrong.

So the option is to do one of the following, after buying a new similar HDD for testing:

1. Install the existing operating system again through Toshiba recovery disks. I have bought Win 7 Pro (full version), but I'm not sure this would work as an upgrade from Vista Home Premium? Otherwise I would have to buy Win 7 Home Premium upgrade (another expense).


2. Do a clean install of Windows 7 Pro


3. Do a clean install of Windows XP Home

Looking into the drivers and installation issue, how complex will this be for (2) or (3) above - how easy will it be to install these drivers or is there something available that can speed up the process rather than doing this one driver by one from your downloads site?

What do you think the most advisable route now?

Answer:Satellite L300-1DN: upgrade or downgrade options

im sure you can upgrade from a full version disk as you could with windows vista disks, so i would vote go with windows 7, but at the end of the day, if you are unable to upgrade from vista to 7 you could alway back up all your data then go for a fresh install as 7 is a million times better than vista and that would also clean your computer 100% so you have a fresh working environment with all your old files etc, but the coice is yours :) hope this helped

Hello, We purchased 3x G480's a few years ago, for our staff in the Philippines.I have got one of these laptops now myself to use for travel.It was running Windows 7 Home x32.I did the free upgrade to Windows 10, and then did a clean install to Windows 10 x64.It is working great, no issues using the standard drivers that Windows 10 came with. It was like a new computer! I noticed that the BIOS was version 40, and I saw that there was a version 96 and version 97 on the site for my laptop. Both had x32 and x64 options, but did state Windows 8. On other laptops, the windows does not really matter for bios upgrades, as they are not specifically linked, so I didnt think it was an issue. I used the version 97 first, but it failed saying "ERROR 255 - TDK library initialization failed!".So I tried the version 96, and that worked. It is now running the later bios. I however noticed that there is no display to push F2 to enter the bios anymore. There is no bios terminal printing on startup, and it now just shows Lenovo screen and a scrolling circle, all the way up to the Windows Welcome screen. The startup time is much slower also. And its chewing through the battery! The battery use to last 4 hours on Windows 7 Home and after the Windows 10 upgrade, but since the bios upgrade I am lucky to get 1h from it. I tried again to install version 97 to see if that would improve things, however I get the same error.So I tried to roll back to version 40, us...

One of my machines has been running 10 for the past 6 months during the insider program, and it is still running 10. This machine used to be a windows 8.1 machine before, though it was originally an 8 machine, and the only install DVD that I have is just that, Windows 8. Knowing that in another month or so I am likely going to start to get activation warnings, I figured I would take some time today (off work) to downgrade and complete the upgrade process. One thing I would love to do, is bypass having to reload 8, and then upgrade to 8.1, and then upgrade to 10. Seems tedious. I would much rather downgrade straight to 8.1, and then upgrade to 10, but to do so, I need 8.1 media. Unfortunately, the media creation tool appears to only contain the option to create install media for 10, given that I am now running windows 10. Anyone know of a way I can get a hold of 8.1 install media? I'd prefer to create a bootable usb drive, but will settle for ISO as well. Thanks in advance.

Answer:I need to downgrade to 8.1, in order to upgrade to 10. Media create?

It sounds like you upgraded from a genuine windows to begin with. You should not need to downgrade. If you are on build 10240 just go to Settings>updates & Security>windows update> advanced settings and click on "stop insider builds" it will ask to confirm and then you will be on the RTM side. If you are already on build 10525 roll back to 10240 and then stop insider builds. I'd try this first, if not over at eight forums in the tutorial section there was a link to 8.1 install media from Microsoft.

Hi guys,

My DVD drive is broken beyond repair, and I've forgotten my USB at home.

I have the installation saved on my desktop, but it won't let me downgrade unless its a reboot. Does anyone have a good multiboot program that will let me install XP on my computer?

Answer:Windows Upgrade/Downgrade with a broken CD slot

Can I ask why you're posting in a Vista forum even though the problem is germain to any operating system?

You can multiboot in Vista and Win 7 as long as you install XP on a separate partition. Have you considered installing XP in Virtual XP which is available for Win 7 ultimate. Then you wouldn't need your drive.

I am getting my W541 today in the mail and was wondering about the use of the downgrade rights. I decided to go with Windows 7 when I purchased, but now after reading more about a 3k screen (which is what I purchased), I feel like 8.1 might suit it better until Windows 10. Would I be able to just install Windows 8.1 on the SSD I am installing, or can I only use the Windows 7 installation disk? Also, would you mind explaining how I would go about installing the OS to my separate SSD that I am installing?

Answer:I have downgrade rights from 8.1 to 7. Am I able to upgrade back up to Windows 8.1 on my SSD?

Grab the installation files for Windows 8.1 here: the correct edition that matches your Windows 7 edition.Burn it to a DVD, and then follow the on-screen instructions to install it to your SSD The product key will be detected automatically from the BIOS.If you need more help let me know. But the process is a little bit difficult to explain. Just follow the on-screen instructions, it shouldn't be too hard ;-)
