More and more players are choosing the PC to enjoy their favorite titles, especially if they have online modes; The drop in the price of graphics cards has motivated many people to make the jump to computers.
Although there are more and more players using Windows, the experience is not lacking in problems; but the last one is perhaps the most worrying, because it has appeared due to an update published by Microsoft itself. Specifically, it is the Windows 11 23H2 update , released in September and which brought new features such as Copilot Artificial Intelligence and support for RAR files .
As the update reaches more Windows 11 computers, more sufferers are appearing on Microsoft’s official forums and on Reddit, complaining that their system now works worse . To this we must add that the Redmond company has not yet made any public statement confirming the problem, which has left users to their own devices to find the solution.
The main complaint concerns the loss of computer performance after installing the 23H2 update. The effect varies greatly between each game and system, and in the worst situations the drop can be up to 23% compared to the performance with the 22H2 update; In other cases, the drop is smaller, between 5% and 8%.
This translates into sudden drops in frames per second in many video games, with differences of up to 20 fps in some scenes; But more worrying is the feeling that the game ‘goes in fits and starts’ , which is not noticeable in the fps but is noticeable in the playability. Some players have also complained that the game has warned them of bandwidth issues if they don’t use an SSD, even though it previously worked perfectly on a normal hard drive.
All of this indicates that there is a background process that is consuming resources, and the culprit seems to be Windows Defender . The antivirus that comes by default with Windows 11 is usually very good, and sufficient for most users; As with all antivirus and programs that scan files in the background, some loss of performance due to busy resources is expected, although Windows 11 is theoretically capable of managing processes to avoid this.
How to solve it
Therefore, the solution that some users have found is to restart Windows Defender so that it starts ‘from scratch’, because everything indicates that the problem is that it is ‘stuck’ and consuming resources in the background.
Unfortunately, restarting Windows Defender is a little more difficult than it seems, and simply restarting your computer is not enough. Below, we go over the necessary steps, although most users will probably be better off waiting for Microsoft to acknowledge the bug and release an update that fixes it.
- Open the start menu and search for ‘Terminal’. Right click and ‘Run as Administrator’
- Paste the following command: Set-ExecutionPolicy Unrestricted
- Paste the following command: Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage
- Restart the computer and enter the BIOS (usually by pressing Del when booting)
- Enable CPU Virtualization in the BIOS. Each manufacturer calls it a different way; Asus and other brands, for example, call it ‘SVM’, while Intel calls it ‘VT-x’.
- Reboot for the BIOS changes to take effect. When you enter Windows, open the Start menu and search for ‘Windows Security’
- In the ‘Device Security’ section, under ‘Kernel Isolation Details’, enable the ‘Memory Integrity’ feature.
- Restart the computer.
