How to Create a Shortcut to Lock Your Computer!!

To create a shortcut on your desktop to lock your computer:

• Right-click the desktop.
• Point to New, and then click Shortcut.
• The Create Shortcut Wizard opens.
• In the text box, type the following:
  rundll32.exe user32.dll,LockWorkStation

• Click Next.
• Enter a name for the shortcut.
• You can call it "Lock Workstation" or choose any name you like.
• Click Finish.

You can also change the shortcut's icon (my personal favorite is the padlock icon in shell32.dll).
To change the icon:

• Right click the shortcut and then select Properties.
• Click the Shortcut tab, and then click the Change Icon button.
• In the Look for icons in this file text box, type:
  Shell32.dll.
• Click OK.
• Select one of the icons from the list and then
• click OK
  

You could also give it a shortcut keystroke such CTRL+ALT+L. This would save you only one keystroke from the normal command, but it could be more convenient.
