Microsoft has distributed an update for Windows 11 , but now players are complaining about performance issues. There is actually a fix that can help somewhat mitigate these problems. The second option is to simply uninstall the troublesome update.
As reported by the colleagues at Techradar, Microsoft has rolled out the 23H2 update for Windows 11. However, along with the update, there seem to be frustrating issues. According to various sources, this primarily affects players with an AMD processor.
With the command line, you should be able to resolve the performance loss issue. The culprit seems to be the Windows Defender, which you should reset. MeinMMO will explain how to do this.

How severe is the performance loss? The issues are mainly related to processor performance. A user on reddit writes that every processor thread works 5-8% slower. In some games, strong stuttering occurs, making them unplayable.
Depending on the game, the 23H2 update can thus have a significant impact on your gaming performance.
How to solve the problem: Microsoft’s official solution proposal is to reset the Windows Defender. You can do this through PowerShell. To open it, press Windows key + X and then click on “Windows PowerShell (Administrator).”
After starting PowerShell, execute the following two commands and confirm each entry with the Enter key:
- Set-ExecutionPolicy Unrestricted
- Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage
With the second command, you reset the Windows Defender and restart your computer.
In a further step, you should check in your BIOS whether CPU virtualization is enabled. It’s best to check your motherboard manual, as every BIOS is structured differently. Ideally, the function is already enabled, so you won’t need to do anything further.
Once you have restarted the system, open the “Windows Security” menu and select “Device Security.” Here, look for the option “Core isolation memory integrity” in the bar and enable it. After that, you’ll need to restart your computer again.
What is the alternative? If all this effort is too much or the process too cumbersome, there is another, quicker way: uninstall the 23H2 update and revert to version 22H2. Then the performance issues should disappear on their own.
However, be aware that you’ll need to disable automatic updates, otherwise Windows will reinstall the update and you’ll face the same problems again.
