I would like to try some registry cleaner because friends told me that regular registry cleaning will keep my computer healthy and prevent many problems that can happen when registry becomes too large and filled up with entries that do not need to be there (like entries for long ago uninstalled programs). I do not care if registry cleaner is commercial (I do not mind paying for good piece of software) or freeware just to be good. So, what registry cleaner should I use?
I can not safely recommend you any registry cleaner. They all can mess things really bad with registry. I will give you few options but you are using them on your own responsibility. If you are looking for commercial solution I would recommend you Registry mechanic from Iolo soft and for freeware solution you could try RegSeeker or CCleaner. Before doing anything with registry cleaners, please, backup registry if you do not want to end up with reinstalling Windows.
