Disable all Windows Security notifications

Overview

About this script

This script improves your privacy on Windows.

These changes use Windows system commands to update your settings.

This script disables all notifications generated by Windows Security.

Windows Security is a built-in Windows feature that offers a unified interface for various security products, including Defender Antivirus 1. This interface was previously called Security Center 1.

By default, local users are notified by Windows Security 2 3. This script blocks these notifications 2 3.

This script may enhance your privacy by reducing visible security-related information on your screen. It may also slightly improve system performance by reducing the processing and display of these notifications. However, disabling these notifications will decrease your awareness of critical security events.

Caution

Disabling security notifications will leave you unaware of critical security issues on your system.

Technical Details

The script performs the following actions:

• Disables push notifications from the Windows Security Center package (Windows.SystemToast.SecurityCenter) 4.
• Configures Group Policy to disable notifications HKLM\SOFTWARE\Policies\Microsoft\Windows Defender Security Center\Notifications!DisableNotifications 2 3.
• Modifies user interface settings to prevent the display of notifications via HKLM\SOFTWARE\Microsoft\Windows Defender Security Center\Notifications 5.

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
