I had problems with moving a directory to C:\Windows\System32\DriverStore\FileRepository and I kept receiving the "access denied" message. I read many forums, watched videos, but nothing helped. So I said to myself "let`s try and trick you, using cmd". So, I started cmd, changed the current path into C:\Windows\System32, saved my folder here, into a new directory named whatever it was easier (let`s say "easy"), and then I wrote this command in cmd:
robocopy /S C:\Windows\System32\easy C:\Windows\System32\DriverStore\FileRepository (/S is for moving the subdirectories). So, this command moved the subdirectory from
C:\Windows\System32\easy into the destination folder. I couldn`t believe it finally worked!! :X Hope this helps
