What Is RuntimeBroker.exe?

RuntimeBroker.exe is a legitimate Windows system process that plays a crucial role in managing permissions for apps from the Microsoft Store (also known as UWP or Universal Windows Platform apps).

Its job is to act as a middleman between UWP apps and your system resources. Whenever a store app requests access to something sensitive—like your microphone, webcam, files, or location, Runtime Broker ensures it follows proper permission rules.

Where Is It Located?

The genuine Runtime Broker file should be found at:

C:\Windows\System32\RuntimeBroker.exe

If it’s located elsewhere, it could be a red flag.

Why Is RuntimeBroker.exe Using CPU or RAM?

Normally, Runtime Broker runs in the background and uses minimal resources, typically under 20 MB of RAM and almost no CPU. However, it may briefly spike in usage when:

  • You open a Microsoft Store app for the first time
  • An app requests a new permission (e.g., microphone access)
  • A background UWP process is triggered by the system

These brief spikes are expected and typically resolve quickly.

When to Worry: Signs of Irregular Behavior

If you notice that RuntimeBroker.exe is using:

  • High CPU (10–40%) for an extended time
  • Memory usage above 100 MB continuously
  • Multiple instances running at once

Then it may not be functioning normally or even worse, it might not be legitimate at all.

Check the File Location

To verify the process:

  1. Open Task Manager (Ctrl + Shift + Esc)
  2. Locate Runtime Broker under the Processes tab
  3. Right-click, then Open File Location

If the file path is anything other than:

C:\Windows\System32\RuntimeBroker.exe

it’s likely a malicious impersonator.

What to Do If RuntimeBroker.exe Acts Suspicious

To be certain that the process is safe, you can perform several simple checks:

  • Check the file location, as we already explained.
  • Check the file’s digital signature by right-clicking on the file in its location.
  • Run a malware scan with a reputable anti-malware program, such as SpyHunter, to make sure that the file hasn’t been altered by malware, or even replaced.
