Avoid third-party registry cleaners for Windows 11 to prevent system instability

Third-party registry cleaners are advised against for Windows 11 PCs as they can cause instability and security risks. These tools, often free, promise performance boosts but can lead to spyware, viruses, and system crashes by incorrectly modifying critical registry keys. Microsoft recommends built-in tools like Disk Cleanup or Storage Sense for removing junk files instead of risking registry edits.
