Instead of going all the way, clicking Start>Turn Off Computer and
selecting Shutdown or Restart, create their icons on your desktop :

create a SHUTDOWN ICON like this :
Right click on an empty area on your desktop.
Select New>Shortcut.
In the first box of the Create Shortcut Wizard, type : Shutdown -s -t 00
Click Next.
Name the shortcut : Shutdown , and click Finish.
Then select an appropriate icon for it !

Similarly create a RESTART icon but follow the folowing step instead :

In the first box of the Create Shortcut Wizard, type : Shutdown -r -t 00
Click Next.
Name the shortcut : Restart , and click Finish.
select an appropriate icon for it now !
