Hi Regaip,

Windows may remove programs during an update for compatibility reasons. If a program is known to cause crashes, bugs, or otherwise conflict with Windows, Windows may remove it to keep your system stable. If this happens, the “All of your files are exactly where you left them” screen will appear like normal–this screen always appears during major updates–but Windows will actually have removed some of your program files.
It looks like this feature is designed to help protect the average Windows user, who might have outdated programs installed. Windows can clean them up and make sure they don’t cause problems. However, Windows doesn’t provide any notice that it’s removed a program–the program will just appear to vanish from your system.

If you run into this problem and you want to get the program back, just reinstall it. In most cases, this will involve re-downloading the program from its developer’s website. You’ll probably be downloading a newer version of the program than the one that Windows uninstalled, so it may just work without any hassle.

Also you can search for the files using Windows Search. Maybe the files have been relocated elsewhere.

Next, confirm that you are signed-in with your own profile and not with a temporary profile. To access your user files, you have to be signed in with your own username or an administrator account.

3] You may want to also check if your files are stuck in some disabled administrator account. Maybe after the upgrade, the files were moved to an admin account which may have now been disabled. To check this, type Computer Management is the taskbar search and open it. Click on System Tools > Local Users and Groups > Users.

Now see if you see any Administrator account which has an arrow pointing downwards. This means that the account has been disabled. Double-click on it open its Properties box and uncheck the Account is disabled check box. Click Apply/OK and exit.
Restart your computer, log in with this account and see if you can find the files.

I hope this helps.

Regards,
Lokesh
