If your shut down is slow, or you want an eaiser way to shut down, restart etc heres how to do it:
First right-click on and empty space on your desktop. Point to New then click on Shortcut. In the box that appears type either (don't type the quote marks) 'shutdown -s -t 00' for turn off, 'shutdown -r -t 00' for restart or 'shutdown -l -t 00'. If you like you can also set an icon for the shortcuts.
