What is RuntimeBroker.exe?

RuntimeBroker.exe is a Windows system process that mediates permission checks for apps installed from the Microsoft Store (UWP). It runs in the background to enforce user consent for resources such as notifications, location, microphone, and camera, and typically exits when no app requests access.

RuntimeBroker monitors permission requests from Store apps and launches with minimal privileges to grant or deny access to resources. It coordinates with Windows security boundaries and ends the session when permission is granted or revoked, helping contain potential misuse.

Quick Fact: Runtime Broker debuted with Windows 8 and continues to mediate runtime permissions for Store apps with low overhead.

How to Tell if runtime-broker.exe is Legitimate or Malware

  1. File Location:: Must be in C:\Windows\System32\RuntimeBroker.exe (or C:\Windows\SysWOW64\RuntimeBroker.exe on some 32-bit systems). Any other path is suspicious.
  2. Digital Signature:: Right-click the file → Properties → Digital Signatures. Should show a signature from Microsoft Corporation or Microsoft Windows.
  3. Resource Usage:: Typically 0-3% CPU and modest memory during permission checks. Constant high usage without prompts warrants a scan.
  4. Behavior:: Should not remain active in the foreground or without permission prompts. Persistent activity may indicate a problem.

Red Flags: If runtime-broker.exe appears outside C:\Windows\System32 or SysWOW64, lacks a valid signature, or runs with sustained high resource use without prompts, scan with Windows Defender or a trusted antivirus immediately.
