It's very strange, I remove Microsoft Teams in Settings, it disappears in GUI, but it stays in WindowsApps and its icon present in system tray. Also didn't succeed to uninstall it wth Powershell.
There is no direct reference to Teams in registry but I think the Chat App present in the Taskbar is responsible for installing the Teams App. Removing the Chat App in the Taskbar may be the solution or we can add the deprovision key for Teams App and test if it gets installed or not.
I just did an experiment: I deleted Windows Store, then connected to internet and checked for updates. I got only updates and Teams Chat wasn't installed. It was installed when I clicked on Continue on main window. Spoiler: screenshots So, I think store app is doing an update to chat app (or the app is pushed when store conects to apps update server).
Of course Store back-end is required to install the Apps through system but In my test I have even removed not just the Store App but even it's Back-end component too. BTW as MS stated Teams Chat App is based on PWA and that's why it requires Edge Update and Edge WebView to work. Try adding this key to block it's deployment Code: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore\Deprovisioned\MicrosoftTeams_8wekyb3d8bbwe]
Can't integrate mail/calender app. Can't figure out what went wrong, checked all the dependencies. No luck.
Change this line in the script from Code: call :AddProvisionedAppxPackage "%InstallMount%\%%i", "Windows Mail", "%UIXaml26_Appx% %CommunicationsApps_Appx%", "%VCLibs14_Appx%", "%CommunicationsApps_License%" to Code: call :AddProvisionedAppxPackage "%InstallMount%\%%i", "Windows Mail", "%CommunicationsApps_Appx%", "%UIXaml26_Appx% %VCLibs14_Appx%", "%CommunicationsApps_License%"
Would you be so kind to remind us the directory of Teams Chat or how to remove the icon of Teams Chat from the taskbar?
The Chat icon present in Taskbar maybe it's just a stub installer to install the actual Teams App, it may be residing inside Windows folder, need to find out. The actual Teams App gets installed to Program Files\Windows Apps. Add this below tweaks to disable and hide Teams. Code: Windows Registry Editor Version 5.00 ; Disable Microsoft Teams App from Installing [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore\Deprovisioned\MicrosoftTeams_8wekyb3d8bbwe] ; Remove Chat Icon from Taskbar [HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Windows Chat] "ChatIcon"=dword:00000003 ; Disable Microsoft Teams Chat [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced] "TaskbarMn"=dword:00000000 Do report me if it's not blocking the installation of Teams App will test further.
The ClientWebExpereicne removal been fixed with yesterday's uploaded ToolKitHelper.exe. Had to rename it's directory before removing it to avoid long path name issue.
MSMG, thanks a lot, you alone worth the whole team of MS developers! Now it's fine, after applying tweak the Chat icon is removed from taskbar and no signs of Teams App downloading/installing visible. Only [HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Windows Chat] was not created and "ChatIcon"=dword:00000003 value was added in [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore\Deprovisioned\MicrosoftTeams_8wekyb3d8bbwe] UPD: I was too fast, it appeared again))
