Well folks, I've sifted through the various programs and have decided to use CCleaner. I like that it is freeware and that it has scads of options. I'm not saying that the rest are crap; I just find CCleaner simple and easy to use. I'm pretty nimble with certain aspects of my PC, but things like this, such as messing with the registry, I need a program to metaphorically hold my hand.
I thank you all for your input. You folks are a wonderful, and trustworthy group. You rock!
