The root of the C drive should be easy to fix, as most of the directories there don't inherit its permissions. You should be able to use Windows Explorer to fix the permissions, but maybe takeown and icacls will be more precise tools for this task. This is the ACL for my C root: C:\> icacls . . NT AUTHORITY\SYSTEM:(OI)(CI)(F) BUILTIN\Administrators:(OI)(CI)(F) NT AUTHORITY\Authenticated Users:(OI)(CI)(RX) BUILTIN\Users:(OI)(CI)(RX) Mandatory Label\High Mandatory Level:(OI)(NP)(IO)(NW) -- David Macek
