I think I have decided that I very much dislike Windows Vista. However, a few things that I always seem to forget where they are that can help me when I’m in a hurry are…

Run program with administrative privileges:

Start > Type the program in the Search Box. (for example: cmd)
Hold Shift + Control then hit Enter.
UAC will then request permission to run as Administrator.

Turn off/on User Account Control:

Start > Type "msconfig" in the Search Box.
UAC will ask for permission.
Click on the Tools tab.
Select "Disable UAC" or "Enable UAC".
Click on "Launch"
