Registry Power Cleaner smartly analyzes your registry. This important step sets it apart from other registry cleaners. Some registry cleaners "over-fix" and permanently delete important pieces of your registry, which can leave your PC in shambles. While other cleaners don't fix enough and leave you with the same PC problems. In contrast Registry Power Cleaner uses cutting edge technology to make smart recommendations on what to repair. In just minutes, Registry Power Cleaner can optimize and improve PC performance, remove harmful errors and help prevent system crashes.
