CCleaner pro usding it for over 5 years not a single problems with the hundreds of cleaning and registries corrections.
   
Great program. Been using for 10+ years. The free version is also very good on it's own for finding and removing junk files especially from web browsers. However it will clear everything in the history so if you want to go back, don't run this program until you finish. Also great at removing any, ahem, embarrassing sites you rather people not know about!

Does what it says; cleans the crap, but be careful when adjusting advanced features. If you do not know exactly what you're doing, leave as is. The new browser is just a browser with specific features, easy to remove when desired. I've installed Ccleaner on every laptop since years. It's great and really trustworthy.
  Nikki   (further information)
Been using it for years. Great for cleaning out junk, and finding bloat. Much easier to use and personalize than most programs, of this type. Wouldn't be without it.
  Doris  
I have had the program fro several years and found it handy to have to clean files, scan the registry, and delete unneeded system restore files.
