Install RSAT tools in a PC with Windows 10 1903…

In a WSUS environment it might be necessary to change a value in the registry to get access online and install the tools:

HKLM/Software/Policies/Microsoft/Windows/WindowsUpdate/AU/UseWUServer to 0 and restart windows update service.

Via Powershell with administrative rights you can install the tools with the command:
Get-WindowsCapability -Name RSAT* -Online | Add-WindowsCapability -Online
