window.

❑ If the Alt+F4 keys do not work, click Start and the Shut down button to turn off your computer.
❑ If your computer does not turn off, press the Ctrl+Alt+Delete keys and click the Shut down button.

If the Windows Security window appears, click Shut Down.

❑ If this procedure does not work, press and hold the power button until the computer turns off.

Turning off your computer with the Ctrl+Alt+Delete keys or the power button may cause loss of unsaved data.

computer.

❑ Try reinstalling the software.
