I have installed that program on quite a few different computers that have been in operation for a long time, and it found over 1000 registry entries that were no longer required and they were removed. I also installed CCleaner, and it found over 6 gig of unnecessary files. I also use other clean up utilities at times, and my computer which is about a year old runs just like brand now most of the time. Of course it has an 8 core i7-860 processor and 8 gig or ram which makes it run smoothly on almost anything that I do. I am not in the mood to do a complete reinstall on my computer, and have never done that in the past. I use Zone Alarm for my Firewall and Avast for my Anti Virus, and have never had any malware in my computer for many years. Of course I am usually browsing sites that have perfect WOT scores. I also use other programs that monitor safety of sites, and if a risky site comes up, I get plenty of warning and get away from it pronto. I have Smart Defrag 2.1 running continuously, and also use CClean after every session before I turn my computer off. I also use Advanced System Care 4 once or twice a week. All of these programs are free and can be downloaded from the Internet.
Do you think Registry cleaners and system optimizers really work?
-- Yes, they make a noticeable difference. (How so?)
-- Somewhat. (How so?)
-- No, I can't tell any difference. (Please explain.)
-- No, they actually made my system perform worse. (How so?)
-- I don't use them. (Any particular reason why?)
