Prevent (New) Teams from Prompting to Register as the Default App for Chats and Calls

Question

We have installed New Teams on a VDI and every time the user gets a new VDI session and it launches Teams, it prompts to "Make the new Teams your default app for chats and calls". We do not want this prompt to ever be displayed. How can we disable it?

We have updated the registry to show this but the pop-up is still displayed:

HKLM\SOFTWARE\IM Providers\Teams FriendlyName = Microsoft Teams

HKLM\SOFTWARE\IM Providers\Teams ProcessName = Teams.exe or ms-teams.exe

Answer 1

I figured it out by updating the Registry. The pop-up is no longer being displayed.

At HKLM\SOFTWARE\IM Providers I added a key called MsTeams, and added these keys within with these values:

FriendlyName = Microsoft Teams

GUID = {88435F68-FFC1-445F-8EDF-EF78B84BA1C7}

ProcessName = ms-teams.exe

Create a key called MsTeams under HKLM\SOFTWARE\IM Providers. Add these string values:
