Reg Hunter _verified_ Jun 2026

(by Sherrod Computers, now often distributed via third-party download managers) is a registry cleaning and system optimization tool for Windows. It scans the Windows Registry for invalid, obsolete, or corrupted entries and offers to fix them to improve system performance and stability. Verdict: Once popular, registry cleaners are now largely considered unnecessary for modern Windows (10/11) and may pose risks. RegHunter specifically has been flagged by some security tools as a "Potentially Unwanted Program" (PUP) due to aggressive marketing and bundling tactics.
