This is how I make a Shortcut to quickly lock-down the Computer\Work Station. I find it useful if I'm suddenly called away and want to make sure Things are just as I had left them. The keyboard Key Combination of " WinKey + L" will accomplish the same thing. To make the shortcut, (right-click) an empty area on the Desktop >>> New >>> Shortcut >>> type in the following command, "%windir%\system32\rundll32.exe user32.dll, LockWorkStation" >>> Next >>> Name the Shortcut >>> Finish. To change the icon, (right-click) Shortcut >>> Properties >>> Change Icon >>> type in the following command, "%SystemRoot%\system32\shell32.dll" and press "Enter" >>> Select an Icon >>> OK all the way back to the Desktop. I starting using this Shortcut because my Cat walked across my Keyboard and killed several hours of Work. Something to think about if there are Kids or Animals around the Computer while Work is being done.
