I have to say, your windows system administrators probably love you for this bit of advice. HOWEVER, installing the Blue Screen Screen Saver is asking for trouble if you have relatively new desktop support technicians at your location.
Case in point, as a young intern several years ago, I would roam our cubicles attempting to make sure that our users were not having problems from time to time. One day, I happened across a computer system with this screensaver enabled, and the user was nowhere to be found. Never having seen the bluescreen screensaver before, I thought it was real, so I wrote down the exception code, and powered down the system. When I powered it back up, of course, the system came up just fine. Woo-hoo, system fixed. ('That was easy'.)
I was fortunate that the user did not actually have any files open that hadn't been saved, and that the system was not corrupted when I forced the power off.
My advice to all: Use a screensaver with a password, but, do not use a screensaver that will make some eager newbie bite, and think he'll be helpful by fixing your computer for you.
