Prevent Teams from Being Installed

[TravisG]

Hey all,

 

So just like the title suggests, I would like to get rid of Teams as we are a G Suite school. Therefore, no need to have it automatically added. If a user needs to use it, they can either install the user-level app, or just use the browser (which is what we do on Windows 10).

 

I'm ripping it out via a PowerShell script during OSD via MECM. But then I noticed that once OSD is completed, Teams gets installed upon the first login. So then I created a logon task to remove Teams using the SYSTEM account. And this works as intended. Then about 4 or 5 days later, Teams is reinstalled. And it's installed as a provisioned app. This tells me Microsoft is adding it back somehow. Just like I stated above, I don't want to completely Teams because there are a few legitimate cases, but for the most part it is not needed, and I'm trying to avoid confusing my users.

 

Here is my code to remove it during logon. I know it's redundant, but it's a catch all, just in case.

 

[color=#D4D4D4][font=Consolas][color=#9cdcfe]$TeamsProPkg[/color] = [color=#dcdcaa]Get-AppxProvisionedPackage[/color] -Online | [color=#dcdcaa]Where-Object[/color] { [color=#9cdcfe]$_[/color][color=#dcdcaa].DisplayName[/color] -like [color=#ce9178]'*Teams*'[/color] } | [color=#dcdcaa]Select-Object[/color] -ExpandProperty PackageName -First [color=#b5cea8]1[/color]
[color=#dcdcaa]Remove-AppxProvisionedPackage[/color] -PackageName [color=#9cdcfe]$TeamsProPkg[/color] -Online -AllUsers -ErrorAction SilentlyContinue
[color=#9cdcfe]$TeamsPkg[/color] = [color=#dcdcaa]Get-AppxPackage[/color] -AllUsers | [color=#dcdcaa]Where-Object[/color] PackageFullName -Match [color=#ce9178]'Teams'[/color] | [color=#dcdcaa]Select-Object[/color] -ExpandProperty PackageFullName -First [color=#b5cea8]1[/color]
[color=#dcdcaa]Remove-AppxPackage[/color] -Package [color=#9cdcfe]$TeamsPkg[/color] -ErrorAction SilentlyContinue -AllUsers | [color=#dcdcaa]Out-Null[/color]
[/font][/color]

 

Is there a registry key or something that tells Windows to install it? Checked the GPOs, but don't see anything but the chat icon. I haven't tried using dism.exe, but I'm sure the above cmdlets are the same as using dism.exe.

 

Any help will be greatly appreciated.
