"In the Metro interface, hover your mouse over the Zoom icon that appears
in the lower right corner of the screen. The Charms bar should then pop
up displaying several icons. Moving your mouse up the screen will reveal
the names of each icon, including Search, Share, Start, Devices, and
Settings. Click the Settings icon and then the Power Icon. You should see
three options: Sleep, Restart, and Shut down. Clicking Shut down will
close Windows 8 and turn off your PC."
