Right click your desktop, click New>Shortcut.
When the wizard pops open, type in:
shutdown -s -t 00
+this will shutdown the PC in 0 seconds or right away.
-s means shutdown
-t XX means in so much time (the XX can be any time in seconds.)
you can also do a reboot or make a seperate icon.
shutdown -r -t 00
-r means reboot
You can then name the shortcut whatever you want.
Also, if you want to customize even more, open a command prompt and type in shutdown, it will list all the options that you can use.
Hope this helps.
You could say I've been around.
