Disable outdated Edge SmartScreen library update

Overview​

About this script

This script improves your privacy on Windows.

These changes use Windows system commands to update your settings.

This script prevents specific versions of Microsoft Edge from updating to the newer SmartScreen library.

This script reverts Microsoft Edge to the previous SmartScreen library, used before version 103 1 2. It blocks Edge from loading the new SmartScreen library (libSmartScreenN), which is responsible for checking site URLs and application downloads 1. By running this script, Edge will utilize the older library (libSmartScreen).

This script is effective only for Microsoft Edge versions 95 to 107 1. It does not function on versions older than 95, which always use the older library 1. Similarly, versions newer than 107 always utilize the newer library 1 2.

Disabling the updated SmartScreen library can increase privacy by limiting data collection but may reduce security as it bypasses the latest updates that combat phishing and malware.

This script may improve system performance since some users have reported slowdowns with the new library 3; these issues have probably already been resolved as the library has matured.

This script applies only to Windows devices within a Microsoft Active Directory domain or managed in similar way 2 3. It is effective only on computers under organizational management, such as those in workplaces or schools. It's not applicable to personal computers that are not managed by an organization.

This script configures the NewSmartScreenLibraryEnabled policy 1 2. Changes will take effect after restarting the browser 1.

Caution
  • This will display the message "Your browser is managed by your organization" on the settings page.
  • Disabling SmartScreen may reduce your protection against phishing and malware.

This script uses Batch (batchfile) scripting language.
