Windows 10: System thread causing high cpu usage

The system process has been randomly using about 15% of my CPU for about an hour then goes back down again. I used the Process Explorer threads tab to see that ntoskrnl.exe!ExTryQueueWorkItem+0x5a20 has been using the most CPU in the system process. Can anyone tell me what that means?Thank you.

system process high cpu usage

Hello,

To fix high CPU usage issue, please refer these steps:

Try to identify the process creating this issue.

Download Process Explorer from Microsoft:

Process Explorer - Sysinternals

Run the tool then select the system process, right-click and select Properties.

Switch to the Threads tab. This will show which file is using the excessive CPU usage, from which you can then attempt to diagnose it.
