What is the best egistry cleaner for Windows 11? The Professional Recommendation: Don't use registry cleaners on Windows 11. Instead:

1. Run these in order:x    
Malwarebytes scan
Autoruns (Microsoft Sysinternals) to audit startups
WinDirStat to find space hogs
Update all drivers

2. If still slow after 1 hour of maintenance:

Backup data
Perform Windows 11 Repair Install (keeps files/apps):
Download Windows 11 ISO → Run setup.exe from within Windows

3. Last resort: Clean Windows 11 install

Registry cleaners are digital snake oil for performance issues. At best, they remove harmless entries; at worst, they break Windows or applications. The few minutes of perceived speed gain are usually placebo effect or from the reboot they force you to do.

Focus on real performance tweaks instead of using registry cleaners for Windows 11. An aging PC likely needs hardware upgrades (SSD, more RAM) or a Windows refresh, not registry cleaning.
