This is due to the fact that our Registry Booster product tackles what we consider to be the most important areas of the registry such as ActiveX, OLE, Software, DLL and System areas which other cleaners do not address. Other registry cleaners may account for different areas of the registry which may total a greater number of finds in less important areas (similar to anti-spyware products which classify hundreds of cookies as security issues). Please look at our comparision sheets for more information.
