Life Sucks, I've heard horror stories like that about registry cleaners, but only from like <1% of people probably.
I have two of them that I use (besides Spybot & Adaware, if those count) called RegCure & Cleanup Utilities 2007. CU2007 seems like a pretty damn cool program. Any comments on those?
Also, when I do the reinstall I will be using my friend's harddrive to backup all my files to. Can I drag my programs that I would like to keep from my computer to his harddrive & back to my computer?? In order to do that could I just drag the program from the 'Program Files' folder into the 'Program Files' folder on my reformatted machine & the programs will work?? Would I be better off doing that or trying to re-dl what programs I can??
