Not the proper place to post this, but since you brought it up;-)
I use CCleaner daily and recommend it to all of my friends. It's free, it's safe and it works. It removes "crap" that you would spend much time and effort getting rid of if you even knew everywhere to look.

(I have no connection with CCleaner, I'm just a fan. Their defraggler is good, too.)
