You're very welcome. I'll start us out. When my coworker left his computer unattended one time, I pressed the "Prt Scr" button and saved the captured image of his desktop.
I then went into the control panel and changed his desktop display to that image. Then I right-clicked the desktop and unchecked the "Show Desktop Icons." Finally, I pulled the Start Menu off the screen.
The result? A perfect replica of his real desktop, with none of the functionality. It was so hard to keep from laughing while watching him not be able to double click anything!
