    How to Go Back to Previous Version of Windows in Windows 10


    When you upgrade to Windows 10 or update to a new version of Windows 10 (ex: Windows Update), a copy of the previous installation is saved to the Windows.old folder in the root directory of the Windows 10 drive as a backup. This backup will allow you to be able to go back to the previous build of Windows for up to a 10 days after upgrading to Windows 10 if you should want to.

    To go back, you'll need to:
    • You will need to have enough free space on the Windows C: drive. Usually the free space needed is at least twice the size of the C:\Windows.old folder.
    • Keep everything in the Windows.old and $windows.~bt folders after the upgrade. This means to not delete these folders, and not check the Previous Windows Installation(s) box when using Disk Cleanup.
    • Remove any user accounts you added after the upgrade.
    • Know the password you used to sign in to Windows 7 or Windows 8.1 (if you used one).
    • Have the USB drive you used to upgrade to Windows 10 (if you used one).

    What you need to know before you go back:

    It will keep your documents, photos, and other personal files, but it can't save:
    • Any apps installed after the most recent upgrade
    • Any changes to personal settings made after the upgrade
    • If you're using a local account, you'll need to sign in to this PC with your old password after going back. This doesn't apply to a Microsoft account.
    • If you go back to Windows 8.1, some apps that came with Windows, like Mail and People, might not work anymore. To fix them, reinstall them from the Store.
    • If you’re a Windows 10 Insider with a Windows 10 preview build installed, going back to an earlier build won’t remove you from the Insider Program. When the next preview build is ready, it'll be installed on your PC.

    If you PC has been flighting longer than 31 days, you'll need to create recovery media and clean install the old OS directly to the machine. Don't forget to back up your data and content first!

    I am in the process of going back to previous build right now. So far it's been running for about 90 minutes but seems to be doing what it should. Does this generally take a while?

    Hello Frank,

    Yeah, it could sometimes take a while to finish. Especially if you had any issues in the current installation.

    As long as you have hard drive activity, you should be good once you wake up from boredom.

    I finally did get it back to the previous build and now I'll do a clean install. As far as the boredom was concerned I solved that problem the old fashioned way--I just took a nap. That worked wonders.

    Hi Shawn,

    I had a Windows 8.1 laptop and used the official 10162 ISO to run Setup.exe within Windows itself. However it won't let me go back. I get an error saying files are missing.

    I don't think I should have done anything to damage windows.old or other files it needs. It's the laptop I was having activation problems with, so I did try entering different product keys, and I also tried to boot the machine's recovery options (but they couldn't find files to restore from), but I'm surprised if I did anything to break the functionality to go back.

    I'd already taken a Macrium Reflect backup so hopefully that will work and it won't be an issue for me, but it does suggest that this function might not something to rely on as a way back.

    Hey David,

    Yeah, I wouldn't rely on it as an only source to go back with.

    Did you use Disk Cleanup, or any similar 3rd party program, that would have removed previous Windows installation files?

    Hi Shawn,

    I'm pretty sure the only things I installed were software I use day-to-day, such as Firefox and Adobe Reader - in fact they may have been the only ones.

    I did try the Manufacturer's Recovery feature (press F9 at power-on and it take you to recovery options), from which I tried restoring a System Image (but it said there was no Image saved) and a Reset from there - but it said it needed installation files to do it. So I don't think either of them should have changed anything.

    It's not a problem for me (assuming my Macrium restore works out) but I'm happy to explore/ test things out tomorrow, if it would help contribute to Forum knowledge, especially as I think quite a few folks may want to roll back to their original OS in order to activate the GA release. :)
