SSPService.exe Heavy resource usage

Windows 10 and Windows 11 are being affected with heavy CPU Usage causing massive delay in nodejs development.

All is related to the Endpoint Protection: Threat Protection policy.

When disabling most of its protection features the system operates in a better standard mode but still affecting time.

After searching for similar cases no solution has been found.

Just to provide a better description: the Policy Exclusion for specific folders does not seem to affect the resource usage nor the performance.

Please help us to solve this issue.

Best Regards,

  • Thank you for reaching community forum. Before we begin, I would like to ask what those machines' role was. What applications running on the system, and are you observing any specific application being launch when you observed the high CPU utilization? 
    Many aspects may cause a high resource consumption on the system with security software installed, for example, incorrect exclusion, application bugs, and malware. Have you also tried applying hotfix on one of the problematic systems?

  • Hi, 

    the systems are dedicated to development activities. Particularly developers using Android Studio and Nodejs experience excessive delay in terms of time to complete each build and as already mentioned elevated CPU Usage.

    All are Windows based systems (10, 11) in several releases, so it does not seem to be related to a specific system update.

    Best Regards,


  • Do you know if any process exclusions have been made for the main executables interacting with files on the system or performing the compiling operations?

  • We are seeing the same thing for all of our virtual machines, be they Windows Server or Desktop OS VMs. More cores will brute force the issue away, but machines that were running fine as of 9/12 received an update late 9/13 to 9/14 in the AM, after rebooting we are seeing the SSPservice.exe use almost 50% of available CPU while the VM sits at idle. Our physical hosts have a plain as day increase in CPU usage that has not subsided from 9/14 that sticks out like a sore thumb from the usual pattern of usage on these hosts. Physical PCs with many cores don't have as obvious of an issue, but the SSPservice.exe is still the chief user of CPU resources on those PCs. We are seeing in VMware VMs as well as VMs hosted in Azure.
