i can honestly say that i've never been caught...i take precautions.
first, that alt+tab bs doesnt work if you've got A LOT of porn on your screen. what i did, was go into a program that looked important (like MSword) open up a term paper then took a screenshot as my desktop. then, i wiped off the oil on my door, so it would creak very loud. before the door can fully open, i bust an windows key+D, and my computer goes to the "term paper" desktop, and it looks like i'm doing work.
oh, and i also take my junk out halfway. it may take longer, but it's safer.
