Can McAfee Fix Registry Errors? | What McAfee Does & Doesn’t Do

McAfee does not include a dedicated Windows registry cleaner. McAfee’s PC optimisation tools focus on removing junk files, managing startup programs, and optimising browser performance — not registry editing. Windows registry ‘errors’ are often overstated in importance, and Microsoft does not recommend third-party registry cleaners.
