TEAMs Autostart up

[sippo]

We have recently installed Apps for Enterprise on our Windows 21H2 image. We cannot find a way of TEAMs not autostarting on login.

 

Any idea's? Can't find anything online anywhere.

Can't comment on auto starting, but there is a user setting for it to start in the background, Just a note, If you use outlook integration for status, it won't kick in until you open teams from the tray.

The reg key it sets up to install Teams per user also makes it auto start (or used to when I last updated our deployments)

 

It’s under (assuming 64bit):

 

HKLM software wow6432node Microsoft currentversion run

 

And it’s the TeamsMachineInstsller key that makes Teams run and if not installed then install

I can't find those in Regedit. Grrr.

 

What we are finding is that teams is starting in Appdata, and with mandatory profiles its a pain.

[Steve21]

It runs from appdata, but the installer is in program files if deployed via 365

 

Or are you deploying it separately?

 

Did you def check the wow6432node bit? Not just current version

 

The other bit that makes it run (but you’d need the one I mentioned above to install it in the first place) is under

 

HKCU software Microsoft windows currentversion run

 

And then it’s com.squirrel.teams.something

 

But that should only get populated if installed by the machine installer in the first place

I've done this, I've no idea why it's so convoluted, Im sure it was a good idea at the time

 

$fixscript = $($env:LOCALAPPDATA + "\DeleteTeamsAutorun.ps1")
$bootstrap= $($env:LOCALAPPDATA + "\BootstrapDeleteTeams.vbs")
$script="Dim shell,command 
command = ""powershell.exe -nologo -executionpolicy bypass -File $fixscript""
Set shell = CreateObject(""WScript.Shell"")
shell.Run command,0"
$script | out-file -FilePath $bootstrap
"start-sleep -seconds 60; Remove-ItemProperty -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Run' -Name 'com.squirrel.Teams.Teams'" | Out-File -FilePath $fixscript
New-ItemProperty -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Run' -Name 'NeverTeamsOnStart' -Type String -Value "$bootstrap" -Force

I cannot find Currentversion under microsoft or wow6432node

[Steve21]

Let me login on a pc and copy paste the links rather than typing

 

 

Right so ->

 

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Run

 

Which should have TeamsMachineInstaller

 

and

 

Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

 

Which should have com.squirrel.Teams.Teams

 

Should be able to copy/paste those above into regedit directly

Working on this myself at the moment, we've done it with the Prevent Microsoft Teams from starting automatically after installation GPO setting.

 

Although if Teams is installed before this setting is set you'll need to run the Teams autostart reset script on a per-user basis to clear out existing autostart settings so it can pick up the GPO.

 

You'll want to make sure you have a recent copy of the Administrative Template files (ADMX/ADML) for Microsoft 365 Apps for enterprise/Office added to your PolicyDefinitions central store too.
