Win 10 22H2 on my laptop Thinkpad X1 Nano.The process 'System' causes an abnormal high CPU usage in task manager, which makes my laptop runs at a high frequency over 3Ghz and on a high temperature.Picture 2: So I open the Process Hacker, there is a 'IoStopTimer' thread in the process 'System', if I kill this thread, the problem solved. But it stills in the next bootWhat the hell is the 'IoStopTimer'? Can I solve this forever?

What are the processes that cause HIGH CPU usage?

 

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.

System Idle Process High cpu usage

No, System Idle Process is *not* causing high cpu usage. It's not causing anything at all.

System Idle Process is not really any process at all. It's just a number inserted to make the total CPU usage add up to 100%. From the little information you've provided, I can't tell what your problem is, but it's definitely not System Idle Process .
