14. YOU CAN LOCK YOUR XP WORKSTATION WITH TWO CLICKS OF THE MOUSE.

Create a new shortcut on your desktop using a right mouse click,

And enter 'rundll32.exe user32.dll,LockWorkStation' in the location field.

Give the shortcut a name you like.

That's it -- just double click on it and your computer will be locked. And if that's not easy enough, Windows key + L will do the same.
