Legacy-Edge-Launcher

This program makes it as simple as a double click (and using UAC one time) to get back to the legacy version of Microsft Edge (Spartan).

Warning

Currently this application does not work any more!

Caution

Edge Legacy does no longer receive security updates and is lacking a lot of widely used features!

How it works

• The app enables Side-by-Side mode Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\EdgeUpdate
Allowsxs = 1
• According to this post Legacy Edge Launcher now also deletes this registry key: SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\ClientState\{56EB18F8-B008-4CBD-B6D2-8C97FE7E9062} -> BrowserReplacement
• The legacy edge binaries have to be copied back
• The new edge has to be uninstalled (Beta Chromium & Legacy Version may be installed side-by-side)

Tech Stuff

Then the app uses the IApplicationActivationManager interface to start Edge Legacy with the following appUserModelId: Microsoft.MicrosoftEdge_8wekyb3d8bbwe!MicrosoftEdge
