Creating a shortcut for switching users or locking your computer in Windows XP !!

The Windows logo key+L is a terrific shortcut for switching users or locking your computer. But if your keyboard doesn’t have a Windows logo key or you prefer using a mouse, you can create a program shortcut that provides single-click access to the same feature. Follow these steps to create a switch/lock shortcut on your desktop:

1. Right-click the desktop and choose New, Shortcut.
2. On the first page of the Create Shortcut Wizard, type rundll32.exe user32.dll,LockWorkStation and click Next.
3. Type a name for the shortcut (Lock Workstation would be appropriate), and click Finish.
4. Right-click the new shortcut and choose Properties.
5. On the Shortcut tab, click Change Icon.
6. In the text box, type shell32.dll and press Enter.
7. Select an icon that tickles your fancy; you’ll find several with lock, key, and user images. Then click OK.
8. In the Shortcut Key box, type the shortcut key you want to use (for example, Ctrl+Alt+L). To immediately display the logon screen (if Fast User Switching is enabled) or lock your computer (if Fast User Switching is disabled), simply double-click your new shortcut or type the shortcut key you assigned. To make it accessible with a single click, even when your desktop is covered with other windows, move the shortcut to the Quick Launch bar.
