Create a Quick Lock Icon
Create a shortcut by right-clicking the desktop. On the pop-up context menu, choose "New", then "Shortcut". Then copy and paste this in the program location box:
rundll32.exe user32.dll,LockWorkStation
Click "Next",
and enter a name for your new shortcut, such as "QuickLock" or whatever. When you double-click that shortcut, you're logged off the network, and has the same effect as logging off. All running and open programs remain intact upon logging back in.
