So basically the title says it all, I managed to corrupt my Windows 10 user profile by trying to apply a theme that was made for a prior version to 1803 (etc... 1709...).

The theme resulted in black screen, with flashing cursor.
My keyboard kept turning numlock(1) on/off. I wasn't able to do anything at that point.
Nothing worked, not even the recovery menu, everything turned completely black.

I was able to recover my log on screen, by removing the theme using Windows 7 in dualboot options... thank god for that. I still backed it all up, just incase I need to re-use that corrupt theme to sort the issue out.

After that I got into something called logon loop. Which basically doesn't let you log in onto your profile because your theme is actually corrupt.

I managed to create a new user profile by replacing utilman.exe -> cmd.exe and use "net user" to bypass my original user.

Got onto Windows 10, everything works fine as it should.

My question is, is there a reg key, or some option that can help me remove that theme onset that I put on my original administrator profile. Or I'ma have to backup this and make a double with pre-saved settings?


Thanks in advance
