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
