Background: This is a desktop with a fresh of Windows 7 64 that was force-upgraded to Windows 10 64 by Microsoft, without my consent.
Just recently had a problem with Grey Screen of Death, so I replaced the video card. I had no ability to remove the driver first because of GSOD. Went from a GTX275 with latest drivers to an 8800GT (what I had lying around).
System booted right up and Graphics are running OK now. When I went to run the Nvidia drivers uninstall, I got "This App can't run on your PC". I downloaded the 8800 drivers (which appears to be the same d/l as the GTX275 drivers) and got the same error trying to run that. I tried to run the previous driver install d/l, which was only a few weeks old and worked fine then, got the same error.
PC passes overnight run of memtest86.
Since then I have tried the following:
Run all apps that fail as administrator. No change, same error.
Many reboots.
Turned off Smart Screen. No change.
Turned off Microsoft Defender. No change. (turns itself back on at reboot).
Turned UAC all the way down. This did nothing, but now I can no longer turn it down any more. It is now locked one notch below full.
Tried to create a new user with Admin privileges. This is the standard fix. Account creation failed with unhelpful error "Something went wrong"
Tried various paths of creating new user including with Microsoft account, all attempts end in Something went wrong.
Reset PC (reinstall Windows 10) results in error "There was a problem resetting your PC. No changes made"
Reboot to Option 7 ran check disk, 100%, booted up. No change, all the same apps still result in "This App can't run on your PC".
Tried to load registry hack for Take Ownership. Regedit fails to launch with "This App can't run on your PC".
There is no prior restore point. (There was under Windows 7)
There is no previous build to revert to.
I'm running out of ideas. I'm ready to save off user data, reinstall Windows 7 and be done with it, but maybe I'm missing something first? Or maybe I'll just move to Mint. Any problems there, I can solve myself.
