Install RSAT 1809+

As of 1809, tools like RSAT (Remote Server Administration Tools) can no longer be installed in the traditional manner, they must now be installed with either DISM or Add-WindowsCapability.

Add-WindowsCapability -Online -Name Rsat.ActiveDirectory.DS-LDS.Tools~~~~

While the above code will install the AD RSAT tools, it’s a little ugly looking. Lets say you wanted to install the whole RSAT tool suite, you’d need to know the name of each of the oddly named tools, or will you?

Get-WindowsCapability -Online -Name RSAT* | Select-Object DisplayName, State
DisplayName                                                                          State
-----------                                                                          -----
RSAT: Active Directory Domain Services and Lightweight Directory Services Tools NotPresent
RSAT: BitLocker Drive Encryption Administration Utilities                       NotPresent
RSAT: Active Directory Certificate Services Tools                               NotPresent
RSAT: DHCP Server Tools                                                         NotPresent

So now we know how to list the tools we want in an orderly fashion, how do we go about installing them in a quick and easy way?

Get-WindowsCapability -Online -Name RSAT* | Add-WindowsCapability -Online
Path          :
Online        : True
RestartNeeded : False

Path          :
Online        : True
RestartNeeded : False

Get-WindowsCapability -Name RSAT.R* -Online | Select-Object DisplayName, State

DisplayName                              State
-----------                              -----
RSAT: Remote Access Management Tools Installed
RSAT: Remote Desktop Services Tools  Installed

And its that easy. Note, if you get the error 0x800f0954, a fix that I have found is to open your local group policy, go to Computer Configuration > System > Specify settings for optional component installation and component repair. Enable this setting and check the box for download repair content and optional features directly from Windows Update.
