Change the Power Button in the Start Menu in Vista
By default, the Power button on your Start menu is set to put your PC in Sleep mode. Though this might be fine for some, you might want the Power button to simply shut down your PC. For example, if you usually choose to shut down your PC instead of putting it into Sleep mode, then you're likely aware that it takes an added click to the arrow on the Start menu to shut down your PC. In other words, it's a waste of time. Reconfiguring the Start menu Power button shaves a few seconds off the usual process.
