Disabling UAC is really not recommended and I strongly advise against it!
Some users find it annoying to get the UAC elevation prompt, every time a program asks for administrator rights. You can disable UAC, so every program is automatically started with administrator rights (of course, the user has to be in the administrators group anyway).
Just go to Start -> Control Panel -> User Accounts and Family Safety -> User Accounts -> Turn User Account Control on or off and uncheck the CheckBox.
