High CPU from System Center Endpoint Protection and Windows Defender

Duchemin, Dominique 2,006 Reputation points


I have System Center Endpont Protection installed on all servers.

I have Windows Defender feature installed on Windows Server 2016, Windows Server 2019, Windows Server 2022 and all Desktops.

How could I permanently limit the CPU usage to 10-15%? not only during SCAN as apparently the settings are just impacting the scans but the CPU is high even at other time ... not sure which other process(es) than the scan starts this service.

    Unfortunately, it's important to note that directly limiting the CPU usage of System Center Endpoint Protection or Windows Defender to a specific percentage, such as 10-15%, is not a standard configuration option. Antivirus software like System Center Endpoint Protection and Windows Defender is designed to use system resources, including CPU, to provide real-time protection and scanning capabilities.

    While you can adjust some settings to optimize resource usage, it's not advisable to forcibly limit the CPU usage of these security solutions. Doing so could compromise the effectiveness of the antivirus protection and leave your systems vulnerable to malware and other threats.
