Installation :: Revert Using (Go Back To Windows 7)

Aug 1, 2015

I installed the upgrade to W10 and I think I should have waited. Things are slow to open and lockups, frozen screens and streaming problems are happening all the time. I see there is a go back to Windows 7 option and I may take it for now, and do a clean install at a later date.

Unable To Revert Back To Windows 8.1?

Nov 11, 2015

I installed the Windows 10 update on the twenty-fourth of October this year. The first thing that I saw was a Rundll32 error or something. Next, OneDrive stopped working. A few days later, GTA V stopped working. Now, the Start Menu doesn't work, meaning if I click the Windows logo, it'll prompt me to sign out to "fix" the problem. So, I tried to go back to Windows 8.1 (64-bit flavor) one week after the update-a quarter of the deadline to update. Instead, apparently "the files that were needed to take you back were deleted", even though they're in plain sight according to file explorer-$SysReset, $WINDOWS.~RT, and $Windows.~WS I believe. Is there anyway that I can go back, or do I have to cough up another $90 to go back?

How To Revert Back To Windows 7 After One Month On OEM Product Key

Nov 28, 2015

I have an OEM Gateway computer and I recently bought a new desktop on Black Friday. I want to revert my Gateway desktop back to Windows 7 and do a factory restart so I may sell it. However, when I try to download the iso from Microsoft, it tells me my key is an OEM one and to contact the manufacturer.

So I went to Gateways website and it says to press F8 during boot and do a bunch of stuff but pressing F8 when it says to does nothing and Windows 10 boots like normal.

Installation :: Could Not Install Revert Back To Windows 7 Failed

Aug 7, 2015

My Windows 7 was updating to Windows 10. When it appeared to almost be done configuring a message appeared stating the Windows 10 could not be installed and it was restoring the previous version of Windows.

Well that did not work. The pc will not boot up now. Instead I get: "Windows could not start because the following file is missing or corrupt: <windows root>system32hal.dll Please reinstall a copy of the above file"

I hope I can add the file using the win7 dvd. I know I was getting low on hard drive space, but had cleared enough to have 4 gig or so free. It was either not mentioned anywhere or I missed how much hd space would be needed. Of course I am assuming that the install bombed due to this?

Installation :: How To Revert Back To Windows 8.1 On A Dell Venue 8 Pro

Sep 20, 2015

So I made the mistake of upgrading my Dell Venue 8 Pro to Windows 10... It's very slow and buggy.

I tried using the built in "Revert back to Windows 8.1" option in the Settings "app", but it says that files have been deleted and it can no longer perform the uninstallation.

I also tried going into the tablet's built in Backup and Recovery from Dell, but that doesn't allow me to reinstall Windows 8. It's merely a diagnostic.

How To Revert Back To Windows 7 With A Broken Start Menu

Aug 19, 2015

want to switch back to Windows 7. However, my Start menu doesn't work. This proves to be very problematic, because the Settings menu within the Start menu seems to be the only path to reverting back to Windows 7. I've tried a few times to get my start menu back in order to restore Windows 7, but nothing I've tried has worked. Here's what I've tried:

(1) Entering a special command in Windows PowerShell [URL]..... Didn't work.

(2) Creating a new account with administrator privileges. Start menu works, but I can't use it to revert to Windows 7. I'm prompted to delete all other accounts created after the upgrade before reverting back to Windows 7.

(3) Accessing the Settings menu from within the Control Panel. Settings menu doesn't seem to be accessible from the Control Panel.

Is there a way to go back to Windows 7 without using the Start menu? I would rather not have to go find my original product key for Windows 7 and reinstall it, but if that's the only way, so be it.

Why No Longer Revert Back To Previous Windows From Tech Preview

Jun 15, 2015

I installed the technical preview on my Surface Pro (gen 1), It's great and all. Gets smoother with each update, however, I'd like to revert back to 8.1 pro so I can reserve my copy of Windows 10.

I don't exactly know if the tech preview will auto-update to the full OS when Win10 releases July29 and I've tried to search for an answer to that question and the answers I find refer to Microsoft releasing "ISOs" when the full OS comes out and I don't know how to do those things so that's why I want to revert back and reserve.

This is my first time trying out OS preview builds. I made a USB recovery drive before I installed it though. I tried using it to refresh my SurfacePro back to windows 8.1 using my USB recovery drive, but the only option I get when it comes to choosing a target operating system to refresh is just windows 10.

How To Revert Back To 8.1 After Upgrading Surface Pro

Dec 23, 2015

After upgrading my Surface Pro from W8.1 to W10, I have discovered the hard way that Windows 10, even in tablet mode, is not touch-centric. (I also think that the W10 UI is much more cluttered by comparison, but I realize that that is a matter of taste.)

How can I revert my Surface Pro from W10 back to W8.1?

Installation :: Partitions After Upgrade - Clean Install And Revert Back

Aug 11, 2015

Recently upgraded to w10 from w8.1 via the upgrade option, then proceeded to make a USB boot with w10 and performed a clean install.

However, something is fishy with my system and w10 so for now i want to revert back to w8.1 via a clean install of w8.1

When i installed w10 however i noticed i have an abundance of partitions, and preferably i would only like to have my SSD and HDD as optional storage spaces. I do of course not want to delete any necessary recovery or system partitions, but to me it seems like i currently have too many.

Which of the partitions in the picture below can i delete? Is it safe to delete all the recovery partitions when clean installing w8.1 from usb? meaning that will the installation create the necessary partitions required by windows?

See picture for info(gjenoppretting = recovery)

Update Deleted Files / How To Get Them Back

Dec 2, 2015

I just updated to windows 10 and when I first started up my computer my files were there, just moved to a different folder(i had to access them through C:/users) I then restarted my computer and now all of files that were on my desktop, downloads folder, pictures, and music folder have all disappeared. Searching for them using Cortana gives no results. Is there anyway I can get them back? Should I try restoring my system to Windows 7?

Deleted The Folder Icon From Taskbar - How To Get It Back

Oct 22, 2015

I accidentally deleted the default folder icon that comes standard with Windows 10 home. Well, I didn't delete it, I hit the "Unpin from taskbar".

Where do these icons go when you unpin them? And how can I get it back?

I know I can replace it with File Explorer, but I like the files that are displayed with the standard folder icon.

Can't Revert To Win 7 - Option Is Not In The System / Security Screen

Aug 18, 2015

Windows 10 has messed up a lot of things that I just don't want to deal with. I'm just a little home user for fun and games and googling and I don't see where 10 is anything more than different. I'm supposed to have 30 days to restore 7 if I choose, but that option doesn't appear where it should.

I also have had a problem with my (former) admin password. The password that I wrote down isn't working (??!!) and I seem to be doomed in limbo between 10 and 7 without it or being able to reset it.

Can Revert To Windows 7 Second Time?

Oct 10, 2015

I like Windows 10 but it caused too many problems, so I used the option to revert to Windows 7. This has also meant a return to getting insistent messages wanting me to install Windows 10 again (and on one occasion, an attempt to install it without my permission). My question is, if I do reinstall Windows 10 and run into the same problems, will I have the option to return to Windows 7 a second time?

How To Manually Revert To Windows 7

Nov 11, 2015

I'd like to perform a manual revert to Windows 7.An elderly client accidentally upgraded what I believe was Windows 7 Home to Windows 10. This was within the last week, and Windows.OLD is still there, but “Go back to Windows 7” is not an option.

(Yes, he was the only user, and he was an admin. For some reason, Windows 10 says it's the Pro edition now. I don't know why. I don't understand why “Go back to Windows 7” isn't present. Client doesn't know what he did, nor what options he selected along the way. Yes, a clean reinstall could be done, but returning to the old setup saves about four hours of other reinstalls and setups.)

Microsoft has a KB971760 "How to restore a Windows 7-based computer to a previous Windows installation by using the Windows.old folder".I'd like to confirm that this same process would work from Windows 10 to Windows 7.

How do I revert this update? Going in safe mode and selecting this update does not give me an uninstall option.So what other solution do I have?

There was no system restore point made prior to this update so that is not a solution.

Get Back After Recovery Brought Back Windows 7?

Oct 10, 2015

I was running Windows 7 and upgraded to Windows 10. I lost no data or programs or pictures, etc. Windows 10 worked fine for about a month and then developed a "restart required" loop. After several attempts I tried the Recovery option, thinking it would take me back to a restore point as in Windows 7. Instead it took me back to Windows 7 and all data and programs (other than the Windows 7 default programs) are gone. How can I get back to either 7 with my data and programs or 10 with my data and programs?
