Can you recommend the best pc cleaner for windows 11?

Here are two best free PC cleaners for Windows 11.

Glary Utilities

If you want something that feels but has more features, Glary is a top choice. It includes over 20 tools for system maintenance.

Best for: Users who want a "One-Click Maintenance" button that fixes shortcuts, cleans the registry, and manages startup apps.

Key Feature: Its "Startup Manager" is excellent for seeing exactly how many seconds each app adds to your boot time.

Wintoys (The Modern Tweaker)

Available in the Microsoft Store, Wintoys is a clean, modern app designed specifically for Windows 10 and 11.

Best for: Improving performance by disabling unnecessary Windows features and services that 25H2 might have turned back on.

Key Feature: The "Health" tab allows you to run "SFC Scans" and "DISM" repairs with one click. These are the official commands used to fix corrupted system files after a bad update.

A Quick Tip for 25H2 Performance

Since you mentioned the PC is "extremely slow" after the update, a best Windows 11 PC cleaner might only be half the battle. Many users on 25H2 have reported that graphics drivers are the main culprit for lag.

Check your GPU: There was a known hotfix (driver version 581.94 for Nvidia users) specifically for 25H2 stuttering.

Give it time: Windows often runs a process called "Search Indexing" for 24-48 hours after a big update. If your Disk Usage is at 100% in Task Manager, leaving the PC on overnight might actually fix the lag.
