Remove Edge Open With associations

Overview

About this script

This script improves your privacy on Windows.

These changes use Windows system commands to update your settings.

This script removes Microsoft Edge associations from the Open With context menu for various file types.

It enhances privacy by reducing Microsoft Edge's integration with the operating system. This limits data collection opportunities during file interactions. It also enhances system stability by removing leftover Edge associations after uninstalling the browser 1. It may improve system performance by simplifying the Open With menu.

Removing these associations gives you control over which applications handle your files, thereby reducing unwanted data sharing with Microsoft.

Caution

Removing these associations may change how certain file types and web links are handled on your system. Remember to set up an alternative browser.

Technical Details

The script targets file extensions such as .htm, .html, .pdf, and .svg, removing their associations with Microsoft Edge in the Windows Registry. These associations persist even after uninstalling Edge (last confirmed with Edge v115 on Windows 11 22H2 and Windows 10 21H1).

The script applies to Windows 10 (version 1909 and later) and Windows 11. The table below shows the default data confirmed by tests:
