This is one of the nifty features of Windows (XP) that no one seems to know about. Before a presentation, I use the “show/hide desktop icons” feature to hide every single item on my desktop. That way if I need to exit a presentation for any reason, the only thing projected is a my desktop wallpaper. After the presentation, I restore all in just one click.
1. Right-click desktop
2. Go to Arrange Icons By
3. Select Show Desktop Icons
4. Let the screen refresh (may take a few moments) and you are left with a completely clutter free view!
