How to Repair High CPU Usage by RuntimeBroker.Exe on Windows 10 PC

Runtime Broker is a trusted process in Windows 10 that manages permissions for apps in the Windows Store. It checks whether all permissions (such as access to photos) are stated in the app and notifies the user if they are allowed or not.

It also checks whether the app has the ability to access hardware, such as a webcam. In short, it’s a kind of middleman between your app and the privacy/security of your Windows 10 PC.

What causes RuntimeBroker.exe’s high CPU load?

Normally, the Runtime Broker process should only use a very small CPU resource or a few megabytes of system memory, but in some cases, a faulty Windows program or third-party software can make Runtime Broker use 100% of CPU up to a gigabyte of RAM or even more. This can cause your Windows 10 computer to be slow or unresponsive.

So if you find that your CPU and RAM are being used very heavily and your computer is running slowly, you are probably having a problem with some application on your computer.
