Overview​

This script disables the System Guard Runtime Monitor Broker service and its associated process.

The System Guard Runtime Monitor Broker service monitors and verifies Windows platform integrity 1 2 3 4. It handles attestation and reporting functions 4 5. It assists assertions of System Guard Runtime Monitor (SGRM) 4. This enables management systems such as Intune and SCCM to collect integrity data 4 6 7 8. It supports remote actions such as blocking access to compromised devices 6 7 8.

The service manages communication between the System Guard and other parts of Windows using Remote Procedure Calls (RPC) 4 5. It uses Event Tracing for Windows (ETW) events, controlling and configuring ETW sessions 4 5. This means the service collects and logs events.

Disabling this service may enhance privacy by preventing system integrity data collection and reporting. It can also boost performance by reducing the service's resource usage.

However, disabling this service may reduce security by preventing Windows from verifying system integrity and addressing threats. This may make the system more vulnerable to attacks. Additionally, using this script on a work or school computer may violate your organization's policies.

Caution

Disabling this service may decrease your system's security and make it more susceptible to threats.

Technical Details​

This script:

  • Disables the service (SgrmBroker).
  • Prevents its process (SgrmBroker.exe) from running.
  • Deletes its executable file (SgrmBroker.exe).

This service is installed by the Windows package Security-Octagon-Broker 9.

The service's process is located at:

  • %SYSTEMROOT%\System32\SgrmBroker.exe 2 5 10 on Windows 10 and Windows 11 21H2.
  • %SYSTEMROOT%\System32\Sgrm\SgrmBroker.exe 3 9 on Windows 11 22H2 and above.

SgrmBroker.exe is one of the user-mode components of the System Guard Runtime Monitor, and runs as a service named OctBroker (or SgrmBroker) 4.

  1. Not Advised

    This script should only be used by advanced users.

    This script is not recommended for daily use as it breaks important functionality.

    Consider creating a system restore point before doing any changes.

  2. Security Trade-off

    This action prioritizes privacy over certain security features. It's not recommended and should only be used by advanced users after understanding its implications.

    Increased Privacy

    Enhanced privacy through reduced data collection and tracking

    Decreased Security

    Some security features will be disabled or limited

    This script can be reversed, this allows you to restore the default system security.
