Being an operating system, Windows 10 is all about tons of processes working hard to get your desired work done. You might have read about Windows processes like Service Host, Desktop Window Manager, and System Interrupts. Each of them has its own superpowers and also the hurdles they create for the users. In this post, I’ll discuss Runtime Broker (runtimebroker.exe), which is another popular Windows process making rounds on the internet.

So, without further waiting, let’s tell you about this Windows process in some detail and help you take care of your personal computer in a better manner. This article is part of our explainer series on Windows Processes.

What is Runtime Broker (runtimebroker.exe)?

In Microsoft Windows, the Runtime Broker process is responsible for managing the permissions for the apps you download from Microsoft Store.

If we talk about the Windows timeline (don’t confuse it with the defunct Timeline feature), Microsoft added a big change with the release of Windows 8. Apart from its infamous UI replicated from Windows Phone, users were introduced to a new kind of apps they could download from the Microsoft Store.

Called Metro apps, you can find them in a more advanced form on Windows 10 and more recently on Windows 11. But now they’re called UWP (Universal Windows Platform) apps.

Just like the classic Win32 apps, the UWP apps can also access different things like mic, webcams, files, etc. But, obviously, Windows just can’t let them use whatever they want, whenever they want; some kind of a check needs to be in place. That’s what Runtime Broker is for.

As a core Windows process, the job of Runtime Broker is to look after app permissions for UWP apps. Thus, you’ll only see numbers crunching in the Task Manager when a universal app is launched because the Runtime Broker process comes into action.

Why Runtime broker uses too much memory?

The Runtime Broker process is infamous when it comes to slurping your precious memory. But the memory leak issue could be caused by one of the many apps it handles.

When idle, its CPU and RAM usage is next to zero. But when Runtime Broker starts working, the CPU usage could go up by 15%, and a few hundred MBs of RAM gets consumed.

But if the memory consumption exceeds 15%, then there is some problem with an app using it.

Is runtimebroker.exe a virus?

No, the Runtime Broker process isn’t a malware or a virus planning to take over your PC. However, given the fact that it uses an EXE file (runtimebroker.exe), some malicious software could masquerade itself as a Runtime Broker process.
