I Run Perfect Optimizer 5. I also have PC Pitstop and Uniblue Registery booster. My computer has real problems and I can't afford to stop and reformat the hard drive and then reload all of the programs for my business at YellowAirplane.com. The Uniblue Registery Booster helped. PC Pitstop Helped, but I still had super crash problems with Windows Explorer and Windows Media Player absolutely didn't work. I also run Microsoft One Care. All of my video production programs just crash. The computer is a piece of junk until I became desperate and bought Perfect Optimizer 5. It found over a thousand registery errors. Multi megs of junk files. Hundreds of privacy data problems and four worms.
Now, after running Perfect Optimizer, most of the programs run without crashing. My internet works way, way faster and I do not have to take five days off of my work just to fix the Microsoft Madness, all of the junk that the Microsoft company should have fixed everytime the program runs. At least One care should have found the errors. Perfect Optimizer is the only program that really made a huge difference in the computers operation, and for some reason, the more often I run the program, the more programs start working again. This is the truth. This program saved me so much time and money it's incredible. C. Jeff Dyrek, Webmsater http://www.YellowAirplane.com
