An icon to switch user fast

If you have enabled the Windows XP feature "Fast User Switching", you can create an additional icon to switch user FAST.

1) Right-click an empty space on your desktop
2) Select the option "new shortcut"
3) Type "rundll32.exe user32.dll LockWorkStation" (Exactly as shown here, but without the quotes. LockWorkStation is case-sensitive.)
4) Click next
5) Type a name for the shortcut (e.g. Switch User Fast) and click finish

This icon is so fast and handy and completely safe that I would recommend dragging it to your Quick Launch bar.
