When you check the Task Manager, you may notice Runtime broker using too much CPU resources. This has been a concern to many Windows users. Those who do not know the runtime broker process even wonder if it is a virus.
About Runtime Broker
Microsoft first introduced the runtime broker process in Windows 8 and has kept using it up to Windows 10. The process is run using the RuntimeBroker.exe executable. It is a legitimate process designed and distributed by Microsoft Corporation.
The Runtime Broker process is linked to the Universal Windows Apps (UWA). These applications came with the operating system, or those installed from Windows Store, and sideloaded apps.
The Runtime Broker process’s main task is to check if these apps and programs have declared all the safety and required permissions to function on your Windows system. If not, the runtime broker will block the applications and inform you about the applications trying to access your system without your permission.
Simply put, the runtime broker acts as a security middleman on your device between the UWA app and your hardware and data.
aSince Runtime Broker is majorly linked to Universal Windows Apps, it normally becomes active whenever you start one of the UWAs on your device. The runtime broker process is not active all the time.
Why Is Runtime Broker Using Too Much CPU?
Runtime Broker has a bad reputation for sporadically increasing CPU load and memory usage on the PC system. This is a big concern to users because increased CPU usage reduces the performance of the PC.
Normally, the Runtime Broker should not use much of your system’s resources. It should use just a small percentage of the CPU and a few megabytes of memory.
Sometimes your antivirus program can cause problems with Runtime Broker, leading to high CPU usage. Besides, a faulty UWA application or one that is incorrectly installed or working incorrectly can cause runtime broker to use high CPU and high memory in the PC – even up to 30% CPU and gigabytes of memory.
Background Task Infrastructure Service, OneDrive, TeamViewer, fresh paint, Windows tips, and notifications, etc., are the usual UWA culprits when you notice high system resource usage by the runtime broker. For example, a faulty YourPhone.exe process can cause the Runtime Broker to spike CPU usage.
How Can I Fix Runtime Broker Using Too Much CPU?
Usually, Runtime Broker is not a virus. However, if the runtime broker is using too much CPU, it may affect your system’s performance. You need to scan your system with a quality antivirus to see if any virus or application files stand behind it. Running the SFC and DISM scans can help repair corrupted system files or fix missing files and solve runtime broker using too much CPU.
Microsoft also suggests killing the Runtime Broker Process if it starts using more than 15% of memory. Restarting the system can also help install any pending Windows Updates that can be causing runtime broker to use much CPU.

Is Runtime Broker a Virus
No, runtime broker is not a virus. It is a genuine and legitimate process that comes preinstalled with your Windows system. Microsoft introduced the runtime process to help users verify the safety and security of UWA applications.
However, since Runtimebroker.exe is an executable, it is vulnerable to virus or malware infection. Some malware can copy the Runtimebroker.exe name and camouflage as the Runtime broker process to avoid detection.
Using a quality antivirus can help you ensure the system errors are not caused by malware. It is relevant for Windows update errors like 0x80070002 or when Avast Blocked Host Process for Windows Services.
Sometimes, you may notice multiple Runtimebroker.exe processes running in the background. This is simply an indication that you’re running more than one UWA app. The runtime broker is checking all of them. But this could also be the doing of a virus, and you need to scan your system to verify if it is not.
Since runtime broker is used to managing apps and programs from Windows Store, it is necessary to protect your privacy and security when running those apps. It would help if you did not disable this process in Task Manager to fix the increased CPU usage error.
