Hello, I've been having this problem with my laptop only recently and I don't know what is causing it. The system does not recognize me as the administrator even though my account is the only one on the computer. Whenever I try to install or delete anything, a message pops up saying access is denied, and when I look at my permissions, everthing is cchecked. I have looked on threads where the advice is to open Command prompt and use "net user adminstrator /active:yes" under adminstrator mode, and it works for those people. However when I try to open command prompt under adminstrator mode, nothing ever pops up. I've tried the alternative methods, but nothing works. I'd really like to use my computer again and have full rights, so any help would be greatly appreciated!! -Thanks!!
