One-by-one we were individually given a horror situation where a pretend client had their computer screwed up in the worst possible ways. It was a desktop pc running windows 7 and it had the power disconnected, the mouse had the right and left buttons inverted, and the screen wasn't inverted but it looked like it because the background was an inverted screenshot. The actual taskbar was automatically hidden. You needed to change all these settings. On top of that there was a Wordpad window open and a script running that was preventing it from closing. You need to figure out that that's what's preventing you from closing the window. It was pretty difficult!
