What Is RuntimeBroker And How To Fix Its High CPU Usage?

Have you ever noticed your Windows computer running at a slower speed than usual and wondered why? If so, it could be due to RuntimeBroker. RuntimeBroker is a process that runs in the background of your system and is responsible for managing the security and permissions of apps installed on your computer. Recently, some users have been experiencing high CPU usage from this process, which can cause slowdowns and other performance issues. In this blog post, we’ll discuss what RuntimeBroker is, how it works, as well as how to fix its high CPU usage.

What is RuntimeBroker?

RuntimeBroker.exe is a process that helps manage app permissions on your PC. When you install an app from the Microsoft Store, or any other location, Windows 10 gives that app permission to run by adding an entry to the Windows Registry. The RuntimeBroker.exe process checks these entries and ensures that the apps have the correct permissions to run.
If an app doesn’t have the correct permissions, RuntimeBroker will prompt you for permission to continue. For example, if you try to install an app that requires administrator privileges, you’ll see a UAC (User Account Control) dialog asking if you want to allow the app to make changes to your PC.
The RuntimeBroker.exe process isn’t a virus or malware; it’s a legitimate part of Windows 10. However, it can sometimes use a lot of CPU resources, which can lead to performance issues on your PC. In this article, we’ll show you how to fix high CPU usage by RuntimeBroker.exe on Windows 10.

How can I fix high CPU usage caused by RuntimeBroker?

If you’re experiencing high CPU usage from RuntimeBroker, there are a few things you can do to fix the problem. First, try disabling any preview features in Windows that you’re not using. Preview features can often cause high CPU usage, so disabling them may help.
If that doesn’t work, you can try ending the RuntimeBroker process in Task Manager. However, be aware that this may cause some apps to stop working correctly. If you do end the process, it will automatically restart when you next reboot your PC.
You could also try resetting the RuntimeBroker by running the following command in an elevated Command Prompt:
regsvr32 /u C:\Windows\System32\runtimebroker.dll
This will unregister the runtimebroker.dll file and then re-register it, which may help fix any problems with the file.

What are some alternative ways to fix RuntimeBroker high CPU usage?

There are a few different ways that you can go about fixing RuntimeBroker high CPU usage. One way is to simply end the process in Task Manager. This will stop RuntimeBroker from running and using up your CPU resources. However, this is only a temporary fix and RuntimeBroker will start up again the next time you restart your computer.
Another way to fix RuntimeBroker high CPU usage is to disable it completely. This can be done by going into your Registry Editor and setting the following key to 0:
Finally, you can try resetting the Windows Store. To do this, open the Settings app, select Apps and then click on Apps & Features. Find the Microsoft Store in the list and then select Advanced Options. Here, you will see an option to Reset the Store Cache which should help reduce RuntimeBroker’s CPU usage.
Once you’ve made this change, restart your computer for the changes to take effect. With RuntimeBroker disabled, Windows will no longer try to access remote resources which should help to reduce CPU usage.
A third way to fix RuntimeBroker high CPU usage is to install all available updates for Windows. Microsoft often releases updates that address specific issues with Windows components such as RuntimeBroker. By making sure that you have all available updates installed, you can help to ensure that your system is running as smoothly as possible.


RuntimeBroker is a Windows process that helps to manage applications and their permissions. Although it can use up a lot of your CPU power, there are some easy ways to fix this problem. Disabling BETA apps, restarting the computer, resetting Group Policies or reinstalling Store apps are only some of the solutions you can implement if RuntimeBroker causes high CPU usage on your device. Always remember to make sure that your system is updated with the latest security patch before trying any fixes!
