Over the years I accumulated new accounts with strange names like All_Users.Windows and Owner.Owner-codenumber. After suitably transferring their contents, I have been able to delete the ORIGINAL accounts, but these two resist deletion and renaming because they are ‘System Folders’. I expect there to be ONE that resists renaming, but TWO seems excessive. These two are in addition to Administrator and they are found in Documents and Settings. Is there any possibility of simplifying/rationalising these account/user names (or at least one of the two) ? If so, how ?
