Overview

This script disables the System Guard Runtime Monitor LPAC (Least-Privileged AppContainer) process.

This process is part of the System Guard Runtime Monitor (SGRM) functionality 1 2.

  • SGRM is a Windows security feature that monitors the system for potential tampering 1.
  • LPAC (Least-Privileged AppContainer) means this component operates in a restricted environment for enhanced security 3.

Its exposes information through:

  • It uses RPC (Remote Procedure Call) functionality 1 2. RPC allows different software programs to communicate, even if they are on different computers. The RPC endpoint can be called by anyone under the IID a13a9961-953f-4157-8a29-e65e29be510d, and makes use of the common Wininet!Http* family of APIs for the requests 1.
  • It communicates over the Internet 1 2. It reports tampering attempts and sends system and regional information to Microsoft 1.
  • It logs information and uses Windows ETW (Event Tracing for Windows) for potential telemetry 2.

It runs automatically in the background, triggered by the System Guard Runtime Monitor Broker Service (SgrmBroker.exe) 1.

This script improves your privacy by preventing Windows from sending system integrity data to third parties. It can also enhance system performance by reducing background processes.

However, disabling this component may reduce system security by removing a mechanism designed to detect system tampering. This may leave the system more vulnerable to certain types of attacks.

Caution

Disabling this feature weakens your system's protection against tampering and unauthorized modifications.

Technical Details

This script:

  • Deletes the SgrmLpac.exe executable file
  • Prevents SgrmLpac.exe from running

The file location varies by Windows version:

  • %SYSTEMROOT%\System32\SgrmLpac.exe 2 4 Windows 10 22H2 and Windows 11 21H2
  • %SYSTEMROOT%\System32\Sgrm\SgrmLpac.exe 5 Windows 11 22H2 and and above

This file is installed by the Security-Octagon-Broker package . It is described by Microsoft as System Guard Runtime Monitor LPAC 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 action allows you to can restore the system security.
