Guide to limit CPU usage of Windows Defender, stop worrying about lag lag when playing games

If you don’t use or just use basic applications like surfing the web, watching movies, this is not a problem. However, if you are playing games that require high hardware resources, lag will be an inevitable phenomenon.

Therefore, today I will show you how to limit the CPU usage of Windows Defender again with just a simple command line with PowerShell of Windows 10.

Step 1: Click on Windows and type PowerShell, then select Run as Administrator.

Step 2: When the window PowerShell appears, copy and paste the following into:

Set-MpPreference -ScanAvgCPULoadFactor 50

At this point, I will have to explain a bit so that you understand how to use it. By default, Windows Defender can use up to 50% of your CPU, and this is also the number 50 at the end of the code above. You can completely change this number to another number depending on the% CPU you want Windows Defender to use.

You can also increase this number to over 50%, but no one wants Windows Defender to use more than 50% of the CPU. But you cannot set this number as low as 0.

This 50% figure as I mentioned above, it means that Windows Defender can use up to 50% of the CPU and this maximum usage usually happens when you perform Full scan (scan deep) or Windows starts automatically when your computer is running in idle mode.

You should also note that limiting CPU usage does not affect the performance of Windows Defender. This means all virus scanning and removal, etc. Windows Defender is still fully implemented and best possible. Limiting the CPU usage will only make the scan complete longer. For example, usually Full scan will take somewhere 10 minutes to complete, now it takes up to 15-20 minutes depending on the% CPU you allow Windows Defender to use.

Compared to disabling Windows Defender, the CPU usage limit is better. If you feel your computer is running slowly every time Windows Defender starts scanning, especially those who are still using traditional HDDs, this is the trick that you should try.

Thank you for watching!
