Disable "Windows Defender Firewall" service (breaks Microsoft Store, "netsh advfirewall", winget, Windows Sandbox, Docker, WSL)

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 Windows Defender Firewall service (identified as MpsSvc 1 2 3 4). This component acts as a gatekeeper for your computer, filtering incoming and outgoing network traffic based on established security rules 1 5 to prevent unauthorized access 3 4.

This service runs the firewall component of Windows 4. It starts automatically 3 and runs the %SYSTEMROOT%\System32\MPSSVC.dll driver 3. This file is also referred to as Microsoft Protection Service 6.

Beyond firewall functionality, it plays an important role in Windows Service Hardening to protect Windows services 7 8. It also enforces network isolation in virtualized environments 7 9.

Disabling this service can enhance privacy by reducing Microsoft's capability to monitor and analyze your network traffic. It also improves system performance by decreasing background resource consumption. However, it may expose the system to substantial security threats 10. This risk is partly mitigated by boot-time filters that are triggered to protect the computer during startup or when the firewall service stops unexpectedly 2.

Restart your computer after running this script to ensure all changes take effect 11.

Caution

Disabling this service causes problems with software that depends on it 12 such as:

• Prevents Microsoft Store app downloads (error code 0x80073D0A 7 13), impacting winget CLI functionality 14.
• Disables netsh advfirewall commands, used for Windows Firewall management 15.
• Disables Windows Sandbox 11 16, an isolated environment for safely running applications 17.
• Disables Docker 18, a platform for developing and running applications in isolated environments 19.
• Disables Windows Subsystem for Linux (WSL) 18, which lets Linux programs run directly on Windows 20.

Overview of default service statuses

OS Version	Status	Start type
Windows 10 (≥ 22H2)	🟢 Running	Automatic
Windows 11 (≥ 23H2)	🟢 Running	Automatic

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
