Sadly, the one my co-workers tend to fall victim to is the F11 in a browser window...they dont realize that they hit it and freakout that they cant undo the fullscreen...till i walk over and hit F11.

i also like to 'window key + E' people that leave their worstations unlocked. Should you do this, make sure to 'ungroup' their windows (via taskbar settings) first....otherwise they undo it with one click.
