Now wait and read it before you revolt.
Windows can suffer from the old CORRUPT PROFILE issue and if your last one and only Admin capable is the one with the corrupt profile, even Microsoft has never issued a tool (or anyone else) to fix it. You get to rip your files out and start over.
Your choice to jump into that tar pit.
I am the sole owner and user of my laptop. When I first set it up, I established 3 'User Accounts' in the Control panel. One account - the one I would be using most frequently - I set up with 'System Administrator' privileges. The other 2 accounts are for guests, and do not have 'SysAdmin' privileges. My problem is that fairly often, I get a pop-up box that says "You require System Administrator privileges to perform this action." This happens when I am trying to make room on my remote HDD by deleting an old backup. It seems that the operating system does not recognize my 'account' - or any other account for that matter - as having "System Administrator" privileges. How can I correct this problem? Using Win7-Home Premium on an HP dv7 laptop. Many thanks for any and all assistance! Happy Holidays to all!
