Many times in the classroom it is necessary to step away from the computer quickly. Your computer may have sensitive information that students should not see and certainly should not be able to modify. The quickest way to protect your computer is to lock it.
Hold down on the Windows key and press L to lock the computer. This will not log you off the computer. All your programs will continue to run as you left them. When you return to your computer, enter your password and you will be right back where you left things.
There is another (slower) way of doing this. Press Ctrl-Alt-Delete and then click the Lock Computer button.
As an extra measure of security, you should setup your computer to automatically lock after a set amount of time. You can do this through the screen saver. There you will find a check box that says On Resume, Password Protect. You should check that box. This will automatically protect your computer if you do not have a chance to lock it manually.
