Thanks for posting this man. You about gave me a heart attack because it crashed my PC and even crashed safe mode. You need to put a better warning about 64 bit versions of Vista. This will render you're system useless unless you know how to go into the registry and manually remove it. I was really pissed off after I did this. I thought "it will crash vista" was just like an explore crash and a simple reboot. A simple reboot doesn't do shit and it will still be messed up even in safe mode. Luckily I got everything taken care of but seriously put a better disclaimer on this!
Like If you use Vista 64 bit and try this "YOU WILL F*** YOUR SHIT UP".
