Yes, apparently Microsoft do have some sort of sense of humour… Or they just haven’t noticed that one of the companies that they recently bought have produced a Blue Screen Of Death screensaver.
For those who don’t know (is there anyone?), the BSOD is the dreaded screen that tells Windows users that their system has crashed. This usually appears about two seconds before you were about to save the last five hours’ work. The screensaver takes your system information and accurately mimics a genuine crash/startup cycle. Perfect for scaring the hell out of anyone who may share your machine! Download it now before Microsoft’s anti-humour police find it!

I used to have one that made it look like you had a virus which was deleting all your programs, up to and including windows. It was quite effective because it took the list of programs from thoses that were actually on the computer. Unfortunatly, beign a screensaver, it stopped when someone ran up in a panic and moved the mouse. Good for confusing people though.
