Registry Cleaner Pro
Full user review
"Did the job, nothing more"
-Sped up my PC and most of my programs by a small amount
-Effects weren't as noticeable as I was expecting
I guess I expected Registry Cleaner Pro to do a lot more than just speed up my PC. I just bought my computer three months ago, so maybe that has something to do with the limited performance boost I received. I'll try scanning my computer with Registry Cleaner Pro again in a few months and report back.
