Registry cleaner? I have anti spy and malware software. Also, anti-virus software. I do disk cleanup often. Now I'm hearing that I need a registry cleaner. What's that?
Oh yeah, I also keep my browsing history completely cleared.
For instance, I'm able to do all the stuff this software claims to do without it…

So, what's so special about it?
Is it just for people who don't know how to use their computer?
