EdgeDeflector is a discontinued, free, open-source helper application for Windows designed to intercept system links that force-open in Microsoft Edge and redirect them to your preferred default web browser. Developed by Daniel Aleksandersen, the tiny tool operated transparently in the background, allowing users to open Windows system links using browsers like Chrome or Firefox. Core Purpose
Protocol Interception: Windows uses a specific system protocol called microsoft-edge:// for various OS-level links.
Bypassing Lock-in: Features like Windows Search, Cortana, the Widgets panel, and system “Help” links are hardcoded to ignore your default browser settings and force-open in Edge.
System Redirection: EdgeDeflector registered itself as the handler for that specific protocol, catching the link and passing it straight to your actual default system browser. The Microsoft Block & Discontinuation
The Patch: In late 2021, Microsoft rolled out Windows updates (starting with Windows 11 build 22494) that explicitly blocked third-party apps from hijacking the microsoft-edge:// protocol.
The Restriction: Microsoft locked the protocol at an OS level, ensuring that only Microsoft Edge could execute it.
Project End: Because bypassing this block would require aggressive, destructive registry modifications to Windows, the developer chose to discontinue the project rather than risk breaking users’ computers. Active Modern Alternatives
