Logging Off and Shutting Down

SHUTTING DOWN THE COMPUTER 
To log off or shut down the computer, click the Start button: Logging off your computer and shutting down your computer are two different things. Remember the analogy of the car: Logging off a computer is like locking the car (the computer is in a stationary mode and you can’t do anything). When you first log in to a computer, it’s like using a key (password) to get in, and when you are done using the computer, you need to log off (the computer will remain on) to make sure no one can make changes while you are away.

By contrast, when you click Shut Down, it is like turning a car’s ignition off. You need to make sure that processes and programs are properly ended and shut down before pushing the shutdown button, just as with a car you have to turn off the ignition before pulling out the key. Click the Start button, then click Shut Down.
Do not press the power 
button to turn off your computer! 
After you have clicked Shut Down, your computer will begin a shut-down process in which it saves things you have been working on, and ends all programs that are running. You may see a window that says, “Windows is shutting down.” When the computer is done shutting down, the screen will go black, and the computer tower will stop making any noise. It is now shut down. It is not necessary to press the power button—your computer will turn off automatically.
Finding More Help 
If you ever find that you need help while using your computer, you can left-click the Start button, and then click “Help and Support.”In addition, most programs on your computer will also have an individual help feature. The Help function may be available from a Help menu at the top of the window, or by clicking a button. Help buttons are usually located in the top-right corner of the window, and may look like a question mark. Help menus often have a search function or pre-prepared FAQs. Most programs also have 1-800 numbers to connect with a technician.
