Windows Vista: Lock Your Computer Quickly

Do you want lock your computer quickly, instead of pressing CTRL+ALT+DEL? There are two tricks you can use, the first and easiest is to press the Windows key + L. You can also create a shortcut on your desktop (or in the Quick Launch area):

• Right-click the desktop, select New, and then Shortcut.
• The Create Shortcut Wizard opens. In the text box, type the following: "rundll32.exe user32.dll, LockWorkStation" (note: the word 'LockWorkStation' is case sensitive), press the Next button.
• Enter a name for the shortcut, such as "Lock Workstation" or choose any other name you like, then press the Finish button.
• I would highly recommend that you drag the shortcut into the Quick Launch area if its enabled. (note: you may need to resize this area it if there are too many icons)
