Runtime Broker High CPU Usage (FIXED): What Is Runtime Broker?

Runtime Broker is a Windows service that runs in the background. This is an essential service that monitors what UWP apps are getting to your system. In particular, all UWP apps have the right to state what tools / system information they receive and the Runtime Broker service ensures that they do not step out of line.

What is a Runtime Broker?

The service is lightweight and you won’t notice if you don’t check the Task Manager. It is also an essential app so it needs to run no matter what. If it is not running on your Windows 10 system, you should not worry.

Runtime Broker uses a lot of processing power from time to time and you can see it spinning in the CPU column in Task Manager however it returns to 0% in a second. The spike in CPU usage can be caught if you open the UWP app and are fast enough to find Runtime Broker on the Task Manager process list.
