Disable SmartScreen libraries

Overview​

About this script

This script improves your privacy on Windows.

These changes use Windows system commands to update your settings.

This script disables essential SmartScreen libraries, limiting their functionality and preventing their use by other programs.

A library is a set of code and resources that help programs operate. A DLL (Dynamic Link Library) contains code and data that multiple programs can use simultaneously.

Disabling these libraries stops SmartScreen operations across applications. This enhances your privacy by eliminating SmartScreen data collection. It improves security by reducing the system's attack surface. It may also improve system performance by freeing up system resources.

However, turning off these libraries may lower your system's defenses against malware and phishing, as it stops the identification and blocking of potentially unsafe content.

This script targets and disables the following specific SmartScreen libraries critical to their operations:

  • smartscreen.dll: This DLL enables core SmartScreen functionality 1. It manages essential SmartScreen tasks, such as performing security checks and evaluating the safety and reputation of files, applications, and web content 2 3.
  • smartscreenps.dll: This DLL supports SmartScreen functionality 4. It facilitates SmartScreen's critical functions, including component management, registration, and lifecycle within a COM framework 5 6.
