Trying to get Microsoft Edge Legacy working on Windows 11

• I have uninstalled Chromium Edge
• I have copied the Legacy Edge files from a copy of Windows 10 2004
• I have deleted the AppData files for Edge
• I have ran the following powershell commands
  Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($.InstallLocation)\AppXManifest.xml” -Verbose}
  Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdgeDevToolsClient | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($.InstallLocation)\AppXManifest.xml” -Verbose}
• I have disabled CodeIntergirty by using this trick Test your Windows app for Windows 10 S - MSIX

Use regSrv32 FileName.dll from an elevated Command Prompt to make available a specific .dll library for the system.

The Legacy Edge is no longer supported by Microsoft, and they have apparently removed the files to get it to work on the OS.

Check File Permissions, that the user has Full Control of FileName.dll.

Is there any way to still run Edge Legacy in Windows 10 (or 11)? - Windows 10 Help Forums

You used to be able to run both Edge Legacy and Edge Chromium by enabling the registry key: HKEY_LOCAL_MACHINE\\SOFTWARE\\Policies\\Microsoft\\EdgeUpdate\\: Allowsxs (DWORD) set to 1 After the April 2021 update (19041.928), Edge Legacy was forcibly remove

So I learned that the reason Edge Legacy no longer runs is due to it being added to Windows Code Integrity, which shuts it down immediately if it's started up.

It will run if you disable Code Integrity, which is an extremely risky thing to do.

Unless someone knows of a way to unblock just Edge Legacy from Windows Code Integrity, then I guess this is a loss for users, and a win for Microsoft. It's a pretty scary thing to me that they can just prevent users from running code like this, I wonder what this means for the future?

Hello Everyone, I am attempting to get Microsoft Edge Legacy up and running on Windows 11 and here is where I am at

• I have uninstalled Chromium Edge
• I have copied the Legacy Edge files from a copy of Windows 10 2004
• I have deleted the AppData files for Edge
• I have ran the following powershell commands
  Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($.InstallLocation)\AppXManifest.xml” -Verbose}
  Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdgeDevToolsClient | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($.InstallLocation)\AppXManifest.xml” -Verbose}

And edge does open but all the UI elements are not showing and it will eventually crash, I have determined that it may rely on the Windows.UI.Xaml.dll file, as it was used for rendering many of the UI elements, so how would I go about adding the UI elements from here to Windows 11? Any help will be appreciated.

This error log may also be useful so I will include it here too - Spartan crashes on Windows 11 · Issue #2 · Legacy-Edge/Legacy-Edge-Launcher

Again any help will be greatly appreciated.
