Disable Defender Antivirus remote configuration

Overview​

About this script

This script improves your privacy on Windows.

These changes use Windows system commands to update your settings.

This script disables Windows Defender's ability to receive remote configurations.

Windows Defender Management uses this feature to remotely control Defender's behavior 1. It uses a Configuration Service Provider (CSP) as an interface between the device's settings and specified configurations 2. CSPs, like Group Policy client-side extensions, enable reading, setting, modifying, or deleting settings for specific features 2. Mobile device management (MDM) service providers commonly use these CSPs 2.

Disabling this feature enhances privacy and user control by blocking remote modifications to your Defender settings. This action may also improve system performance by reducing background processes related to checking and applying remote configurations.

However, this action may reduce security by:

  • Preventing potentially important security updates from being applied automatically.
  • Limiting the ability of IT administrators to manage Defender settings across devices.
Caution

Disabling this feature may make your computer less secure and reduce the ability of management systems to adjust security settings automatically.

Technical Details​

The script targets the COM registration for the CLSID 195B4D07-3DE2-4744-BBF2-D90121AE785B 1 3. This application registers the DefenderCSP.dll library 1 3. This component is used by the Defender service (MpSvc) 4. The DLL file is located in the %PROGRAMFILES%\Windows Defender folder 1 3.

This script performs a soft deletion of:

  • The COM registration for the CLSID (195B4D07-3DE2-4744-BBF2-D90121AE785B) 1 3.
  • The DefenderCSP.dll file.

For more information on related configurations and the full range of settings affected, see the official Microsoft documentation on the Defender CSP 5.

This script uses Batch (batchfile) scripting language.

Use with Caution

This script is only recommended if you understand its implications. Some non-critical or features may no longer function correctly after running this script.

Implementation Details

  • Language: batch

  • Required Privileges: Administrator rights
