Here's a quick way to shut down or restart your puter, by making a shortcut
right-click your desktop scroll to 'new' then 'shortcut'
in the wizard that pops up type (for Shutdown):
Shutdown -s -t 00 <-Those are Zero's after the -t (then click next, and name it Shutdown or whatever)
for Restart do the same and type in:
Shutdown -r -t 00
make a custom icon for 'em and Drag em to your Quick-Launch bar, and you have a quick n easy one-click way to Shutdown or Restart (not that clicking the 'Start' button and doing it the traditional way is hard or anything, this just makes it faster:)
Enjoy!
