What is the best clean up app for Windows 10/11 PC?

I vote for Microsoft PC Manager, a free official optimization and cleanup app from Microsoft designed to help keep Windows 10 PCs tidy and running smoothly. It brings together a bunch of maintenance tasks, like clearing temporary and unused files, managing storage space, and offering quick access to performance-related settings; all from a single dashboard instead of having to hunt through different parts of Windows.

The best free Windows 11 PC cleanup tool also includes a boost feature that frees up RAM and removes clutter, and integrates with core Windows services so you can manage updates and basic protection features in one place.

Pros

• Official and free: It’s developed by Microsoft and available at no cost, with no bundled third-party ads or software.
• Centralized tools: Combines several system maintenance functions. Storage cleanup, app and process overview, and quick access to Windows security and updates in one place.
• User-friendly: Simplifies common cleanup tasks for non-technical users and provides visual feedback on space used and memory freed.

Cons

• Modest cleanup impact: The “boost” and cleanup features provide only small, incremental gains over Windows’ built-in tools like Storage Sense or Disk Cleanup.
• Limited advanced options: It lacks deeper customization and powerful cleanup options that more experienced users might expect from dedicated optimizers.

If you want a simple, Windows 11/10 cleanup app for PC that’s safer than third-party alternatives and easier to use than hunting through built-in tools, PC Manager is worth trying, especially on Windows 10/11 OS  that need occasional housekeeping without complexity.
