I updated my laptop's OS from Windows XP to Windows 7. There are some leftover files from Windows XP on the computer now. If I try deleting them I get the following error:
You need permission to perform this action.
You require permission from S-1-.... to make changes to this folder.
What's weird is that I am logged in with the only user account on this machine and I have administrator privileges. I tried turning UAC off, but I still can't delete the files.
How can I force removal of these files?
