Disable System Guard sandbox monitoring

Overview

About this script

This script improves your privacy on Windows.

These changes use Windows system commands to update your settings.

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.

This script uses Batch (batchfile) scripting language.

Not Advised

This script should only be used by advanced users. This script is not recommended for daily use as it breaks important functionality. Do not run it without having backups and system snapshots.

Implementation Details
  • Language: batch

  • Required Privileges: Administrator rights

  • Compatibility: Windows only

  • Reversibility: Can be undone using provided revert script
