Windows Defender would affect system performance, here is a solution

Do you feel like your system isn’t delivering the performance it should? It may not be a figment of your imagination.

According to the work of Kevin Glynn, a programmer associated with the site TechPowerUp behind ThrottleStop and RealTemp software, a bug in Windows Defender would have a significant impact on processor performance.

Up to 4.5% CPU resource hogging

Kevin Glynn first noticed this by comparing results obtained under Cinebench R23 which were 1,000 points lower than they should be on the processor used (Core i9-10850K).

While digging, he noted that Windows Defender took up 4% of CPU resources. A problem that has been noticed on Windows 10 like Windows 11 and on all generations of Intel processors between 8^e and the 11^e. On the other hand, AMD processors are not affected.

However, it seems that the Intel hardware is not really in question and Kevin Glynn rather points to a concern with Microsoft’s software alone. A concern that he proposes to circumvent while waiting for a possible patch.

A solution… while waiting for Microsoft

First of all, it is obviously necessary to know whether or not your machine is affected by the problem. For this, it is possible to launch various measurement tools and compare to other tests. More simply, you can download Counter Control.

The application does not require installation and, once launched, all you have to do is take a look at its interface: if the code “0x222” is visible, it means that Windows Defender is playing spoilsport. Clicking on the “Reset Counters” button will remedy the situation.

Unfortunately, you have to restart the thing each time the system starts. Kevin Glynn therefore offers another solution: the ThrottleStop tool on which you can activate the “Windows Defender Boost” option and which you can launch when the PC starts. Of course, all this while waiting for Microsoft to offer us a possible patch.
