Upgraded to Windows 10 Saturday Night.
Sunday morning started computer and the desktop had none of my icons, shortcuts, etc. I found all my files in C: Users. I placed all my files in 1 folder on the desktop. I re added the shortcuts to my programs.
I then updated and restarted. When it came back the desktop was black and had my old shortcuts from 8.1. The files I placed on the desktop were now gone.

I used Shadow Explorer and found the files again in Users, but the Export of files gives corrupt files.

What the heck can I do?

Should I recover back to 8.1?
