How Many Runtime Brokers Should Be Running

Why does Window 10 run the Runtime Broker program (RuntimeBroker.exe)?

As part of Windows 10, Runtime Broker checks to see if all permissions (such as access to photos) are stated in an app and if they are, it notifies the user.

What Is Runtime Broker Windows 10

Runtime Broker, a trusted process within Windows 10, manages app permissions. An application’s permissions are checked, and the user is notified if the application is allowed or not (for example, if it is allowed to access Photos). It also checks whether an app is allowed to access hardware, like the webcam. It is a middleman between your application and your Windows 10 PC’s privacy/security.

Runtime Broker Multiple Instances

As you’ll see in the screenshot above, I have multiple instances of Runtime Broker running. That’s because I was using several apps at the time. These permissions could include access to the camera, microphone, files, and so on.

It is used to determine whether universal apps you got from the Windows Store–which were called Metro apps in Windows 8–are declaring all of their permissions, like being able to access your location or microphone. Though it runs in the background all the time, you will likely see its activity rise when you launch a universal app. You can think of it like a middleman hooking your universal apps with the trust and privacy settings you’ve configured.
