For power user you may wish to disable Windows Vista
UAC which can be annoying for every day general use. The constant security
alerts are most likely not an issue for the average home user but the power
user does not wish to be reminded every two seconds that opening or changing
an item is a security risk.
From the control panel follow these steps:
Uncheck "Use User Account Control (UAC) to help protect
your computer" and click "OK".
