also from the life saver – three buttons CTRL - ALT - DEL options. This option goes well with the HIDING THE LOG OFF FROM START MENU… (To shut down ur system:-without using frm shut down menu) The solution is that u can switch user thru task manager (alt+ctrl+del) or by pressing winkey+L where u get the option to turn off ur compy/restart/stand by.

or u may create a shortcut using this shortcut location to shutdown ur sys %windir%\system32\shutdown.exe -s to restart, u can use this shortcut %windir%\system32\shutdown.exe -r
