Hi, thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.
I understand the issue you have, there is nothing to worry I am here to help, have you noticed any changes before the issue starts? or have you made any changes? while waiting for your response, this issue occurs when there are third-party services that might interrupt the CPU usage or there is a CPU overheating, and for us to sort out the issue, kindly follow the steps below:
Method 1. Do clean boot:
A “clean boot” starts Windows with a minimal set of drivers and startup programs, so that you can determine whether a background program is interfering with your game or program.
- In the search box on the taskbar, type msconfig and select System Configuration from the results.
- On the Services tab of System Configuration, select Hide all Microsoft services, and then select Disable all.
- On the Startup tab of System Configuration, select Open Task Manager.
- Under Startup in Task Manager, for each startup item, select the item and then select Disable.
- Close Task Manager.
- On the Startup tab of System Configuration, select OK. When you restart the computer, it's in a clean boot environment.

Method 2. Run memory diagnostic tool: The memory diagnostic tool is a RAM test to check if there are any RAM issues which can also lead to high CPU usage.
- Press Windows key + R then type in mdsched.exe hit OK then restart the device.
Note: If the issue persists, I suggest contacting a local technician to physically check the processor or do a re-pasting of thermal paste to optimize the processor.
Let me know how it goes and I hope that helps.
Bernard
