As a tech expert, I understand how frustrating it can be to experience 100% CPU usage on Windows 11. It can slow down your computer, affect your productivity, and even cause it to crash. But don’t worry, in this troubleshooting guide, I’ll show you how to fix the issue in just a few simple steps.

Identify the Culprit

The first step in fixing high CPU usage is to identify the culprit. To do this, open the Task Manager by pressing the Ctrl + Shift + Esc keys simultaneously. Then, click on the “Processes” tab to see which applications are using the most CPU power.

End Resource-Intensive Processes

Once you’ve identified the resource-intensive processes, you can end them by right-clicking on the process and selecting “End task.” Be careful not to end any critical system processes, as this can cause your computer to crash.

Disable Background Apps

Background apps can also cause high CPU usage, so it’s important to disable any unnecessary ones. To do this, go to the “Settings” app and click on “Privacy.” Then, scroll down to the “Background apps” section and toggle off any apps that you don’t need running in the background.

Update Drivers and Windows

Outdated drivers and Windows updates can also cause high CPU usage, so it’s important to keep them up to date. To update your drivers, go to your computer manufacturer’s website and download the latest ones for your specific model. To update Windows, go to the “Settings” app and click on “Update & Security.” Then, click on “Windows Update” and select “Check for updates.”

Perform a Clean Boot

If none of the above solutions work, it’s possible that a third-party application or service is causing the high CPU usage. To troubleshoot this, perform a clean boot by opening the “System Configuration” app and selecting “Selective startup.” Then, uncheck all the boxes except for “Load system services” and “Use original boot configuration.” Finally, restart your computer and see if the issue is resolved.
