I have run sfc, DISM and still files were not being fixed so I downloaded a windows 7 iso, created a usb of win7 and ran the upgrade thinking that would fix the files in a jiffy. Well that worked perfectly little did I know that it would wipe the key and prompt me. The bottom of this laptop has seen better days so the sticker is marred. Attempted to clean but that's not helping. The only option left is a backup I have. Is there a way to get the key from the backup? I also ran restore the backup but that did not put the files with the key.
