I loaded Windows Vista as soon as it was posted on MSDN. I like it a lot but I couldn’t stand the constant confirmation of everything I did. The UAC is the piece that is supposed to keep your mom from doing something stupid. But for a guy like me that never doesn’t anything stupid I feel as though I really don’t need it. This article is a great explanation of UAC.
BTW, to turn off UAC go to Control Panel | User Accounts | Turn User Control on or off.
