I only have one account (named, but by default Admin - User Accounts shows it as an Administrator, and there are no other accounts). However, when I try to move/copy files to other folders, I get the message that "You'll need to provide administrator permission to move/copy", and in addition, when I run certain programs (ex, SpeedGuide.net's TCP Optimizer) I get the message -- The current user account does not have permissions to change all the necessary settings. Please start the program with administrator priviledges (right-click and "run as administrator" under Vista/Windows 7, or login as the administrator under older versions of Windows). I have found references to corrupt profiles in searching the issue, but that is clearly not the case here - this is a fresh and clean install. Thanks much for any assistance!
