Eng. Alessandro Mazzanti: Windows 10 - How to install RSAT on version 1809

In previous old blog article I already discussed about RSAT installation procedure.:

Powershell - Manage AD through Command line

Secondly I pointed opportunity to manage server only from your workstation/client executing all server plugin avoiding to connect to each server via RDP (security aspect) and having a single point of management with all rsat tools.

Server - How to Execute RSAT snapins with different users without server/client logon necessity

With new Windows 10 version (1809) something changed slightly.

Here it is powershell installation procedure:

In any case there are other alternative procedure to get same result:

Execute Windows Powershell with administrative rights and launch this command to verify that no RSAT tool is really installed
Get-WindowsCapability -Name RSAT* -Online
Using below command information would be formatted in a more readable way:

Get-WindowsCapability -Name RSAT* -Online | Select-Object -Property DisplayName, State
To add a single tool you should use below syntax:

Add-WindowsCapability –online –Name “Rsat.ActiveDirectory.DS-LDS.Tools~~~~0.0.1.0
To add all available Rsat tools this is syntax correct:
Get-WindowsCapability -Name Rsat* -Online | Add-WindowsCapability –Online
To install only disabled RSAT components, run:

Get-WindowsCapability -Online |? {$_.Name -like "*Rsat*" -and $_.State -eq "NotPresent"} | Add-WindowsCapability -Online
If you got below error it should be due to Wsus internal server pointing:

Add-WindowsCapability : Add-WindowsCapability failed. Error code = 0x800f0954
In this case you should execute
regedit.exe -->
HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU

Changing UseWUServer key to 0 and restarting Windows update service.

Restart-Service wuauserv

And then launching this command:

Get-WindowsCapability -Name Rsat* -Online | Add-WindowsCapability –Online
Afterward rollback previously UseWUServer key value and restarting Windows update service

Restart-Service wuauserv
You could execute below powershell command:

$currentWU = Get-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU" -Name "UseWUServer" | select -ExpandProperty UseWUServer
Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU" -Name "UseWUServer" -Value 0
Restart-Service wuauserv
Get-WindowsCapability -Name RSAT* -Online | Add-WindowsCapability –Online
Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU" -Name "UseWUServer" -Value $currentWU
Restart-Service wuauserv
