Disable SmartScreen Enhanced Phishing Protection warnings and prompts

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 user interface for Enhanced Phishing Protection on Windows.

Enhanced Phishing Protection is a feature in Windows 11 that aims to protect users from phishing attacks 1. This feature monitors the passwords you enter and warns you if a site may be malicious 1.

This script prevents Enhanced Phishing Protection from displaying warnings and prompts. It does not stop the underlying monitoring but disables only the visual warnings and prompts.

This may enhance privacy perception by reducing monitoring notifications, though background monitoring continues. It may slightly improve system performance by disabling these UI elements. However, you will not receive warnings about potential phishing attempts, increasing your risk of falling victim to such attacks.

Caution

This action reduces your ability to detect phishing attempts.

Technical Details​

The script sets the following registry value: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WTDS\FeatureFlags!BlockUxDisabled 2 3.

This feature is unavailable on Windows 10 and Windows 11 21H2 1. It is enabled by default on Windows 11 3 (confirmed by tests on version 23H2 and later).

This script uses Batch (batchfile) scripting language.
