Microsoft Teams NEW can now be installed on Server 2019. Server 2016 is unfortunately not supported.

Firstly, enable these GPOs:

Computer Configuration > Administrative Settings > Windows Components > App Package Deployment:

• Allows development of Windows Store apps
• Allo all trusted apps to install

Download the MSIX Package: https://go.microsoft.com/fwlink/?linkid=2196106

Install Package:

Dism /Online /Add-ProvisionedAppxPackage /PackagePath:”C:\temp\MSTeams-x64.msix“ /SkipLicense

Tip: If you are having issues adding the MSIX Package, try removing the package first:

Get-AppxPackage -AllUsers -Name MSTeams | Remove-AppxPackage -AllUsers

Install MS Edge Webview2, which is also needed:

Evergreen Standalone x64: https://developer.microsoft.com/de-de/microsoft-edge/webview2/?form=MA13LH#download

Download button inside WIndows Updates greyed out? This could be because of a GPO which sets the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate

SetDisableUXWUAccess 0 (1 greyed out)

If you want to apply the settings without restarting your server/computer, restart Windows Updates service.

Have you ever gotten this annoying error when trying to open old control panel settings from the new settings app? This usually occurs in a domain environment.

You can fix this by creating a Domain policy or locally through secpol.msc > Local Policies > Security Options > User Account Control: Admin Approval Mode for the Built-in Administrator account:

If you are having performance issues with your brand new File Server running on Windows Server 2019, particularly when working with small files over a network share, these PowerShell commands might save hours of troubleshooting.

Get-NetAdapter | Set-NetAdapterAdvancedProperty -DisplayName “Large Send Offload Version 2 (IPv4)” -DisplayValue “Disabled” -NoRestart

Get-NetAdapter | Set-NetAdapterAdvancedProperty -DisplayName “Large Send Offload Version 2 (IPv6)” -DisplayValue “Disabled” -NoRestart

Get-NetAdapter | Set-NetAdapterAdvancedProperty -DisplayName “Recv Segment Coalescing (IPv4)” -DisplayValue “Disabled” -NoRestart

Get-NetAdapter | Set-NetAdapterAdvancedProperty -DisplayName “Recv Segment Coalescing (IPv6)” -DisplayValue “Disabled” -NoRestart

Get-NetAdapter | Set-NetAdapterAdvancedProperty -DisplayName “Receive Side Scaling” -DisplayValue “Disabled” -NoRestart

Get-NetAdapter | Restart-NetAdapter

Note: The VM’s network adapter will be restarted, there will be a downtime of about 10 seconds.

On a Windows Server with RDS feature enabled, you might encounter an issue with Windows Update Coordinator being stuck at “Please wait while the application is preparing for the first use” during a program installation. This problem is very easy to resolve with Group Policy Editor (either locally through gpedit.msc or Domain Group Policy).

Navigate to Computer configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Application Compatibility and enable the setting “Turn off Windows Installer RDS Compatibility”.

After installing the program, I would recommend re-enabling Windows Update Coordinator by disabling the GPO setting or leaving it at “Not configured”.
