When you click the Windows 7 Start button you will see an actual "Shut Down" button rather than a cryptic icon- an icon that in Vista, puts your system to sleep instead of turning it off. But you can change the icon's function. Here's how.
1. Click Start, type Power Options, and press [Enter]
2. Click Change plan settings for you selected power plan, and then click Change advanced power settings.
3. Expand, first, the "Power buttons and lid" tree, and then the "Start menu power button" tree.
4. Change the setting from Sleep to Shut Down.
5. Click OK; close the remaining windows.
Now, when you click Vista's little Power icon in the Start menu, it will truly Shut Down your Computer.
