Disable Tamper Protection

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 Tamper Protection feature.

Tamper Protection is a security feature that blocks unauthorized changes to key Defender Antivirus settings 1 2. These settings include real-time protection 1 2, behavior monitoring 2, and cloud-delivered protection 1. By default, Tamper Protection is enabled 1. It is available in all editions of Windows since Windows 10, version 1903 3.

Disabling Tamper Protection may increase privacy and control over your system by allowing you to:

• Change protected Defender Antivirus settings to enhance privacy 1 3
• Disable Defender Antivirus entirely 1 3 to increase privacy
• Improve system performance by adjusting or disabling certain security features

However, turning off Tamper Protection may reduce your system's security by:

• Making your device more vulnerable to malware that attempts to disable security features
• Allowing potentially harmful changes to important security settings

With Tamper Protection enabled, users can modify protected settings through the Windows Security app 1. Disabling Tamper Protection allows changes through scripts and third-party apps such as privacy.sexy 1.

Technical Details

This script modifies the following registry keys:

• HKLM\SOFTWARE\Microsoft\Windows Defender\Features!TamperProtection 4 5 6.
• HKLM\SOFTWARE\Microsoft\Windows Defender\Features!TamperProtectionSource 7

These keys interact with the MpClient.dll library within Defender Antivirus 8. The script sets values to replicate changes made through the Windows Security interface 5.

Tests reveal the following values for various Windows versions:

Key	Opearting System	Default	After toggling ON	After toggling OFF
TamperProtection	Windows 10 Pro (>= 22H2)	1	5 4 6	4 4 6 7
TamperProtection	Windows 11 Pro (>= 23H2)	1	5 4 5	4 4 5
TamperProtectionSource	Windows 10 Pro (>= 22H2)	No value	No value	No value (Or 2 7)
TamperProtectionSource	Windows 11 Pro (>= 23H2)	5	2	2

TamperProtectionSource value 2 means that the Tamper Protection is based on signatures. Other recorded values in various installations include ATP 9, Service Init 10, Intune 11, and E5 transition 12. However, these values lack official public documentation 13.

To check the current Tamper Protection source, use this command:

wmic /namespace:\\root\microsoft\windows\defender path MSFT_MpComputerStatus get /format:list | findstr "TamperProtectionSource"

Or this PowerShell command:

Get-MpComputerStatus | Select-Object -ExpandProperty TamperProtectionSource

This script uses Batch (batchfile) scripting language.
