Runtime Broker High CPU Errors FIXED! [Latest 2021]

Though we all use Windows, many are not very familiar with the system related apps which often run in the background and are launched as soon as you switch on the device. One such app is the runtime broker. which is necessary for managing the permissions for the various applications you download from the Windows store. However, we rarely need to access the application. But problems with overheating of the CPU or the excess use of the CPU memory is primarily caused by this app which significantly draws CPU memory in the background. The Runtime Broker high CPU memory error can happen for many reasons. When the app uses more than 15% of the CPU memory in the background it is considered problematic and can lead to problems like overheating and lagging of the device.

Here we have discussed the possible reasons behind this problem and how you can get rid of the trouble easily. When you have the basic technical aptitude, implementing any of the solutions suggested here will be easy and you can ensure that your device is lag-free and running smoothly once more. From removing unused applications to disabling the windows tips and tricks option, there are several ways the problem can be solved, provided you know the primary reason behind it which is discussed in the next segment.

What Can Cause The High CPU Usage Of Runtime Broker?

The runtime broker errors can occur at any time for several reasons. Especially when the device is loaded with many heavy-duty applications that use the CPU memory largely, this error is witnessed frequently. To solve the error, finding out what is the root cause is elemental. Here we have listed some of the reason which led to this error in your device in the first place:

  • Reports about CPU overload have started coming up since early 2012 and from 2015 among Windows 10 users. Primarily it uses a lot of memory when there is a faulty app in your device and it is the case of the overloading.
  • The runtime broker can use up to a gigabit or more of your RAM when there is a faulty app running in the background.
  • Also, when the antivirus settings conflict with the Runtime broker app and its function it can result in high CPU memory usage.
  • When the different windows services may seem unrelated conflict, it results in lagging and also causes the runtime broker app error.
  • When a service, in particular, is facing any Internal error the high CPU usage is the sign and eventually can be lagging.
  • The runtime broker app when affected by a virus can also cause such errors as high PU memory usage.

These are more or less the various reasons for which the runtime broker error occurs. If you detect the right reason, you can quickly solve it. We have shared the relevant solutions in the next section and depending on what is causing the trouble, you can implement any one of them easily.

How can I fix Runtime Broker High CPU Usage on Windows 10?

Now that you know the prospective reasons behind runtime broker troubles, it is time to learn ways of fixing it. There are several ways in which this can be done and if you master the techniques thoroughly, you can solve the trouble in the minimum possible time. The following are the different runtime error fixes which you can try out, provided you know the reason that led to the problem.

Quick Temporary Fix:

In case you are facing the Runtime Broker high CPU usage issues, there is a temporary and quick fix to implement. When the CPU usage is more than 15% of the memory, this fix can be very useful. But how to recognize the issue?

When the computer is becoming slow, it indicates the high RAM usage and the key is finding ways on minimizing the load on the CPU. The following are the steps for doing so:

  • Press Ctrl+Shift+Esc to open the Task Manager and go to the Processes Tab and check the memory usage of the Runtime Broker App. In case it is using more than 15% of the memory, then you will have to close the app.
  • Look up the Runtime Broker app from the list of apps that are using the CPU memory from the processes list.
  • Right-click on the app and from the drop-down menu select the End task option which will close the app. Once the app is closed, restart the machine.
  • Once you have restarted the machine the app will be refreshed and relaunched but will not add to the lagging of the device. 

However, this is a temporary fix as eventually, the app load will increase once more after using the PC for some time and when this keeps happening, you will need a more robust solution.

Changing the Registry:

Many users report that simply changing the registry had shown positive results and the high CPU usage could be avoided. The runtime broker High CPU trouble can be fixed this way but again, this is not a long-term solution and the CPU problem will be recurring even after implementing this solution. Here’s how you can execute the procedure:

  • Press Windows+R and then in the respective dialogue box, enter “regedit” and then press enter to open the Registry Editor.
  • A dialogue box will come up confirming whether you are willing to run the program and risk modification of certain data. Click on Yes to continue.
  • In the next window, look up and open HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/TimeBrokerSvc.
  • Here you will find the option Start DWORD Entry and right-click on it. Once you right-click there will be a drop-down menu from where you need to select “Modify”.
  • In the next dialogue box which opens, change the value data to 00000004 and the base should be hexadecimal. Then click on OK.

  • This will optimize the performance but do note that it will also affect some of the Cortana Reminders.

Check whether the runtime broker high CPU error has been fixed. In case the trouble persists, you will have to disable several other programs which are associated with the runtime broker app as well.

Disable Windows Tips:

You can also face the Runtime broker errors with high CPU usage because of too many notifications and programs running in the background. Even a task like Windows tips can lead to CPU heating and in such a situation, the best thing to do is disable this service for some time. Here’s how to do it:

  • Go to Windows Settings by Pressing Windows+I and choose the option systems.
  • Under this, click on Notifications and actions and look up “Get tips, tricks suggestions as you use Windows.”
  • Uncheck the box beside it and save the changes.
  • Restart the computer and check the CPU Speed once more.

Disable The Peer-To-Peer Update Option:

With the help of the peer-to-peer update option, you can easily download updates from another computer. But this can also cause the runtime broker windows 10 high CPU error and in such a situation, it is wiser to disable it. To improve the CPU Speed, disabling this feature can be done following the steps shared below:

  • Open settings by pressing Windows+I and then look up and click on Update and Security.
  • Once you click this option, on the next page look for Delivery Optimization and disable the feature “Allow downloads for other PCs”.
  • Now you can access updates to download only directly from Microsoft. But at the same time, the problem with high CPU usage will be resolved.

If this had been the root of the trouble, the problem should be solved permanently unless you turn this feature on once more.

Delete Other Related Applications Like Groove Music And Onedrive:

Apps by Microsoft which you rarely use may also lead to the runtime Broker high CPU error as they run in the background. By disabling them you can recover the CPU speed to some extent. Groove Music is one such music streaming app in Microsoft. Though the service has been discontinued, the app remains and is known to increase the CPU usage in the Runtime broker. The following are the steps to disable this app.

  • Type “PowerShell’ in the search bar and right-click on the app in the start menu and then run as administrator.
  • Next click on Yes when the dialogue box asks if you want to allow the app to make changes to your device.
  • A blue window of the administrator of PowerShell will open where you need to type in “get-appxpackage *Microsoft.ZuneMusic* | remove-appxpackage “and then hit Enter.
  • The Groove Music app will be removed.

Check the CPU speed once the app has been removed. If the trouble persists, try removing the OneDrive next. OneDrive is Microsoft’s cloud-based storage app. Many users these days have other cloud storage solutions like Google Drive and if your OneDrive is rarely used, you can simply disable it because this is also responsible for the runtime broker high CPU windows 10. The following are the steps to remove the OneDrive application:

  • Type cmd in the start bar and then click on Run as Administrator.
  • Like before, press yes to confirm that you want to allow the app to make changes to your device.
  • In the next dialogue box, enter “taskkill /f /im OneDrive.exe “, and click on Enter. This will disable all the processes related to OneDrive.
  • However, to uninstall it in a 32-bit system you will have to enter, “%SystemRoot%System32OneDriveSetup.exe /uninstall “and then hit enter to uninstall. In a 64-bit system you need to enter, “%SystemRoot%SysWOW64OneDriveSetup.exe /uninstall “and then click on Enter.

The problem with High CPU usage should be resolved after removing both these apps.

Check your Antivirus:

Often the interference caused by your security system can also lead to the runtime broker errors. The high CPU usage can be the combined effect of this interference and other applications running in the background. To solve the trouble, check the settings of your antivirus software and then disable some of them as required. Check the speed of the CPU has been increased. In case the problem persists, you will have to disable the antivirus or uninstall it.

Often the problem is resolved after removing the antivirus which is a good sign but also indicates that you will need to use a different antivirus software. Look for a lighter application that does not overload the CPU and then install that instead to avoid the CPU usage problems which eventually slows down the device.

Last but not the least, make sure the Runtime broker is not affected by any virus which can also lead to the problem of slowing down the device. The following are steps to check whether the Runtime broker is a virus:

  • You can easily check this by locating the runtime broker file by checking whether it is located in c:\windows\system32\.
  • You can do this by pressing ctrl+Shift+Esc and open the Task Manager.
  • From there locate the runtime broker under processes.
  • Right-click on the Process and then select the open file location.
  • The file should be located in Drive C inside Windows and System 32 folder. any other location indicates that it is a virus. For confirmation, upload this file to any online virus-checking application like Virustotal.

Once you are confirmed that it is a virus, run your antivirus to get rid of it. Then check the CPU speed which is likely to improve after this issue is resolved.

Frequently Asked Questions ( FAQ's)

Why is the runtime broker using so much CPU?

The runtime broker high CPU error is often caused by the lock screen background. Moreover, the runtime broker runs in the background all the time and it can consume significant CPU memory.
