The Windows 11 preview update KB5044384 is causing issues for users by introducing a bug that impacts Task Manager's metrics, resulting in PC slowdowns. This error affects how CPU, memory, and disk usage data are displayed, leading to inaccurate diagnostics.
Task Manager and System Errors
Beyond incorrect data displays in Task Manager, users report visual glitches and app crashes. The issues are primarily reported in the Processes tab, complicating troubleshooting. The problem is not isolated, suggesting recurring stability challenges with recent preview updates.
Corporate Implications and Updates
The persistent bugs have significant implications for enterprises considering upgrades from Windows 10, which ended support in October 2025. Industries that rely heavily on IT stability, like finance and healthcare, may face delayed adoption due to these issues.
Current Remedies and Future Fixes
Microsoft recommends restarting Task Manager or using Command Prompt or PowerShell to terminate explorer.exe. Users can also rollback the update via Settings, though this means missing new features. Microsoft has confirmed the bug and plans a patch in an upcoming mandatory update.
