Windows 10: Windows 11 CPU "bounce" because of "system" Process

Hello,I've update to Windows 11 and I noticed a strange behavior from System process. As you can see in the screenshot below, I've closed all apps but the "system" process is keeping jumping between 8 to 13%, see the "saw" below. Any suggestion on what could be the cause? For the rest is a super update ;

System and compressed memory background process persistently consuming high CPU resources

Hi,

Thank you for posting in Microsoft Community.

Please answer these questions to get more clarity on this issue:

1. Did you make any changes to your computer prior to this issue?

2. Which anti-virus program is installed on the PC?

High CPU usage occurs for various reasons, for example: virus/malware infections, out-of-date drivers, anti-virus programs or other third-party programs, etc;

Method 1: Windows has a built-in troubleshooter to check and fix issues with system. I would suggest you to run this troubleshooter to check if the issue is with your System
Maintenance.

Refer these steps:

• Press Windows key +X, select Control panel

• Change the view by option on the top right to Large icons
• Click on troubleshooting and click on the view all option on the left panel

• Run the System Maintenance troubleshooter

Method 2: Check if the issue resolves in
Safe Mode.

Refer this article to boot to safe mode:

Steps to reduce the CPU usage.

1-Press "Ctrl," "Shift," and "Esc" on your keyboard. This brings up the task manager without any intermediary screen.

2-Click the "Processes" button on the task manager.

3-Click the "CPU" column header until the arrow next to the label points down.

4-Right-click a program you recognize that uses a high percentage of the CPU and click "End Process." Click "End Process" to reconfirm. This eases up on the CPU's load. Use this step if you're not using a process or if the process has stopped responding. Do
not use this procedure for windows processes.

Hope this helps. If the issue remains unresolved, please get back to us and we would be happy to help.

Thanks.

 

Fix high CPU usage by TiWorker.exe process in Windows 10

I noticed this today, too. I was not doing anything, Chrome was open but on a static page. Closed Chrome and still noticed high CPU usage. Sort Processes by CPU and it was bouncing 20-30%. Reading that it is the update process so I ran Windows Update
and there were no updates. I did not look at network activity but CPU Usage declined a little but WTF is is still using so much? And why is it ALWAYS running?

"Critical" suggests it will crash the system if terminated. I killed the process without any issue.

 

System Idle Process CPU Allocation?

Hi,

I am Sumit, an Independent advisor and a Microsoft MVP here to help.

System Idle Process, as the name suggests is a process that indicates CPU is idle and is not being used, aka is at rest. This is done to totalize CPU usage to 100 between the processes.

So you do not have to worry about anything.
