From Windows 10 to 11: Understanding Your CPU’s Mixed Signals


“Why is there a discrepancy in CPU usage readings between the Task Manager and system monitoring applications after upgrading from Windows 10 to Windows 11? Despite Task Manager indicating 8% CPU usage, my monitoring widgets are showing significantly lower figures, such as 1%, and they do not reflect heavy CPU usage, remaining at 1-5%. These widgets functioned correctly prior to the upgrade. It’s important for me to monitor my CPU, network, disk, and RAM usage accurately, especially on my secondary screen. All metrics except CPU usage are displaying as expected. What could be causing this issue?”


After upgrading from Windows 10 to Windows 11, you might notice inconsistencies in CPU usage readings between the Task Manager and other system monitoring tools. This can be puzzling, especially when such tools worked flawlessly before the upgrade. Let’s delve into potential reasons for this discrepancy and how to address it.


Compatibility Issues

: Some system monitoring applications may not be fully compatible with Windows 11, leading to inaccurate readings. It’s essential to ensure that all your system tools are updated to the latest versions that support Windows 11.


System Resource Allocation

: Windows 11 introduces changes in how system resources are managed. This could affect how CPU usage is reported by different applications.


Background Processes

: The upgrade process might have altered the behavior of background processes, affecting overall system resource usage.

Troubleshooting Steps


Update Monitoring Tools

: Check for updates for your system monitoring applications to ensure they’re optimized for Windows 11.


Reset Windows Security App

: Performance issues, including CPU usage discrepancies, have been reported after upgrading to Windows 11. Resetting the Windows Security app and enabling the Memory Integrity feature may help.


Check for System Updates

: Ensure that your Windows 11 is up-to-date with all the latest patches and updates, which can resolve known issues.


Clean Boot

: Performing a clean boot can help identify if third-party applications are causing the discrepancy.


System File Checker

: Use the System File Checker tool to repair missing or corrupted system files that might be causing the issue.


The discrepancy in CPU usage readings is likely due to a combination of compatibility issues and changes in system resource management introduced by Windows 11. By following the troubleshooting steps outlined above, you can begin to diagnose and resolve the issue. Remember, keeping your system and all applications up-to-date is crucial for ensuring accurate monitoring and optimal performance..
