Can you recommend the best pc cleaner for windows 11?

Microsoft PC Manager.

It is the official system optimization utility developed by Microsoft to provide a safer, native alternative to third-party cleaners. Unlike other Windows 11 PC cleaning tools that may interfere with critical system files, this app functions as a centralized dashboard for existing Windows maintenance features, combining RAM optimization, disk cleanup, and security management into a single, lightweight interface. It is particularly effective after major updates like Windows 11 25H2, as it is designed specifically to handle the modern Windows file structure without the risk of over-cleaning.

1. Download and install the app for free from the official Microsoft Store page or the official pcmanager.microsoft.com website.

2. On the Home tab, click the large blue Boost button. This instantly flushes temporary files and terminates non-essential background processes to free up system RAM.

3. Click on Health Check to perform a manual analysis. This will scan for system logs, recent file lists, and potential issues. Review the "Items to clean" and "Startup apps to disable," then click Proceed.

4. Navigate to the Storage (or Cleanup) tab and select Deep Cleanup. This is vital after a 25H2 update because it identifies "Windows Update Cleanup" files—leftover installation data that can exceed several gigabytes. Select the categories you wish to clear and click Proceed.

5. Under the Apps or Startup section, toggle off any software that you don't need immediately upon login. This is the most effective way to fix the "boot takes forever" issue you described.

6. Go to Settings within the app and toggle on Smart Boost. This allows the app to automatically clear temporary files when your RAM usage gets too high or your junk files exceed 1GB.

Microsoft PC Manager is the best PC cleaner on Windows 11 that excels at streamlining your PC's performance by organizing Windows' own powerful maintenance tools into one click. It is the best choice for users who want to clear update-related lag and reduce boot times without the complexity or intrusive ads found in traditional third-party cleaners.
