ErrorWiz is a program designed to completely clean your PC’s registry with a few clicks of the mouse. Unlike registry cleaners, this goes one step further and cleans your entire PC's hard-drive.  If you are having problems with your PC running slowly, ErrorWiz promises to help detect missing, obsolete, and corrupt entries that need to be repaired or removed from your registry or hard-drive.
