High CPU usage at idle. Win 10 Pro

Hi Julius -

I'm Jerico T., one of the Independent Advisor and a fellow Windows 10 user like you. I understand that you're having some issues right now, let us sort things out.

Prior to the issue, have you made any recent changes on your computer? At some times, high CPU usage during idle is not a problem, high percentage of CPU indicates that a large amount of process power is not being used, however, if your computer slows down due to the high CPU usage, then please try to perform the troubleshooting methods below and check if any of the methods will fix your concern.

Method 1: Perform Clean Boot

• This process will eliminate 3rd party application running in the background of your computer along with services that are not needed to run windows. If there's any conflicting 3rd party application that causes the issue on your computer, this process will stop it.

1. Open the run box by pressing the Windows Key + R and type msconfig
2. System Configuration Utility box will open and by default you are on general tab.
3. On the General tab, click the selective startup and make sure that load system service and load startup items both have checked mark.
4. Click on services tab
5. Put a check mark on Hide All Microsoft Services > This is a very important part as if you miss to click on this, computer might not boot properly or permanently and will end up on clean installation.
6. Once Hide all Microsoft Services have checked mark on it, click on Disable All
7. Click on the Startup Tab and click open task manager. This will open another window which contains all your startup applications on the administrator account.
8. Disable all application that you're not using. You can simply just click on them and select disable.
9. Click OK , Apply and close the configuration utility.
10. Restart your computer and check if the issue still persist.

Method 2: Perform SFC Scan and Repair Windows Image

-This process will perform scan for any corrupted system files or integrity violation and will attempt to repair it along with the Windows Image.

1. Open command prompt with administrator access
2. Type each command below and wait until scan is completed.

sfc /scannow

DISM /Online /Cleanup-Image /CheckHealth

DISM /Online /Cleanup-Image /ScanHealth

DISM /Online /Cleanup-Image /RestoreHealth

Quick note: While the command is running, it's expected to see the process stuck at 20 or 40 percent. After a few minutes, the process will complete successfully.

Once you complete the steps, the Deployment Image Servicing and Management tool will connect to the Windows Update servers to download and replace any damaged files in the local image for Windows 10 as necessary.

3. Close the command prompt.

Feel free to reach back if you need any further assistance.

Hope this help. Have a good day.

Thank you.

Hi, Claudeir, thank you for the response. I tried the things you listed, though it did not help. I managed to capture the usage of some services here in the photo below. As soon as I move the mouse, they tend to go away and not use any CPU anymore.

There was a Windows update pending, although it showed up only after I

clicked ''Check for updates'' and installed it rather quickly after clicking.

Have you tried uninstalling DriverBooster, to be honest you shouldn't need that.

I wouldn't think it would do what you describe either, I have the same.

If all drivers/software are up to date from MSI (for the motherboard) then perhaps a test with a clean boot.
