Click Apply and Reboot the System
If a Clean Boot resolves the high CPU usage issue, then try to find out the exact software which was interfering. You will have to do this manually by enabling/disabling each process or startup.
When finished testing, Ensure you uncheck Safe Boot option in boot tab; otherwise you'll continuously start in a Clean Boot State. Click Apply, Ok
Reboot the system
- Remove all peripheral devices from the system (e.g. printer, fax, etc..) one by one to determine if this resolves the issue. If it does, the device may need to be replaced if updating the driver does not work.
- Update the Wifi drivers in Device Manager. If that doesn't work, reinstall Wifi drivers - sometimes this maybe the problem.
4) The Performance Monitor is a good built-in tool that lets you monitor
and study how applications you run affect your computer’s performance, both in real-time and by collecting log data for later analysis. It is quite useful in identifying and troubleshooting high resources utilization by processes and in
generating a System Health Report of your Windows. But at times, you may
feel the need to use a third-party freeware tool for controlling such processes which may use a high CPU.
