Without any best PC cleaner for Windows 11. Considering a reset or a fresh install is a valid and often effective option if your Windows 11 system is experiencing severe slowness that can't be resolved through cleaning or optimization. It’s not a traditional "best PC cleaner for Windows 11," but it’s the most thorough way to ensure your system is clean, optimized, and running at its best.

When to Consider a Reset or Fresh Install
Persistent Performance Issues: Boot times, app lag, and File Explorer delays remain even after cleaning.
System Corruption or Bloat: Your system has accumulated unnecessary files, broken registry entries, or malware.
Upgrading to a Clean State: To eliminate lingering issues from previous OS upgrades or software conflicts.

How to do it:

2. Create a bootable USB drive.

3. Boot from USB and follow installation instructions.

4. Format your drive during setup for a completely clean system.
