Follow these steps to get rid of high CPU usage in Windows.
1. Press windows key + R and type msconfig into the text box that appears then hit enter on your keyboard, this will open up a configuration window for your computer where you can find all the different options available.
2a) Click on the option labeled Startup tab, if it isnt already selected
2b) In order to make changes easier when using msconfig go under General settings category and tick both boxes namely Load startup items. This makes sure that any time you boot up your PC running from Windows 8 or 10 every program is loaded automatically. Doing so eliminates most causes of high CPU usage due to programs being launched as soon as you start up your computer which uses unnecessary resources during startup process causing slow performance shortly after turning on machine before software has been fully opened
3) Go back one level by clicking Exit (top left corner).
