I've been experiencing high CPU usage which has been affecting basic tasks. When I open up Task Manager, My CPU rises up to 100% for a couple seconds, then settles down to 80-90%. My Memory is also pretty high with it being 97% . I only have Microsoft Edge open. Is there any way for me to fix the performance?

Hi EO,

I'm Sumit, here to help with your query on the Microsoft Q&A forums.

Apologies for any inconvenience you are experiencing. I am happy to help you today.

It seems like an application is causing this.

Does the issue persist in a clean boot state?

Type “msconfig” (without quotes) and press Enter.

In the System Configuration window, select the Services tab.

Check the box next to “Hide all Microsoft services”. Ensure you do it carefully, and not disable all Microsoft services.

Click on “Disable all”.

Select the Startup tab and click on “Open Task Manager”.

In the Task Manager window, select each startup item and click on “Disable”.

Close Task Manager and click on OK in the System Configuration window.

Restart your computer.
