How to Shut Down Your Computer in Windows Vista
You may want to shut down your computer completely when you're done for the day, but Windows Vista gives you a few different options when you want to turn off your computer. Never fear, the following simple steps show you how to quickly and easily shut down your computer completely with Windows Vista.
Click the arrow to the right of the Lock button in the Start menu.
Click the Start button for the Start menu to appear.
Choose Shut Down.
If you want to shut the computer down completely, choose Shut Down, but if you want to reboot (turn off and turn back on) your computer, choose Restart. If you’re going away for a while but don’t want to have to go through the whole booting up sequence when you return, click the Hibernate button. When you get back, just click your mouse button or press Enter, or in some cases (especially on some laptops) press the Power button; your computer springs to life, and whatever programs and documents you had open come back.
Don’t simply turn off your computer at the power source unless you have to because of a computer crash. Windows Vista might not start up properly the next time you turn it on if you don’t follow the proper shutdown procedure. If your computer freezes up for some reason, before you just unplug it, press Ctrl+Alt+Delete twice in a row, or press the power button on your CPU and hold it until the computer shuts down. Be sure that unplugging it from the power source is your last resort.
