How do you take full screen off?

Answer 1

Most of the time it is just simply hitting the Esc button on your keyboard.

If that doesn't work, right-click with your mouse on the screen and see if there is a possibility of shutting down the full screen.

Answer 2

You can press F4, F10, F11 or F15, depending on which computer you use. Failing that, if you have Windows 7, you should see a toolbar just above your scroll bar. Click Tools, and look down until you see the full screen option. Click on it and it should correct itself. If you run out of options and it really annoys you, take your laptop in to be fixed.
