Enabling RSAT tools for Powershell

When installing RSAT Tools, you may encounter the error Error 0x800F0954. This occurs because the system cannot contact the Windows Update server, as the computers are set up to download updates from a WSUS server. This error will occur regardless of whether you install via the GUI (Settings - Apps - Optional features - Add a feature - RSAT: Active Directory Domain Services and Lightweight Directory Services Tools) or via PowerShell. To resolve this, follow these steps:

1. Open regedit as an admin and navigate to: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
2. Find UseWUServer and change the value to 0.

Once the change is made, Windows Update needs to be restarted. You cannot restart the computer, as the GPO will update regedit back to its previous state upon a reboot.

Open a PowerShell prompt as an administrator:

net stop wuauserv

Then run:

net start wuauserv

Now you can install RSAT Tools via PowerShell (must be run as an administrator):

Get-WindowsCapability -Name RSAT* -Online | Add-WindowsCapability

If you only need specific packages, follow these steps:

1. First, get a list of the packages that can be installed:

   Get-WindowsCapability -Name RSAT* -Online
   

2. Run this command and insert the package you need in __:

   Add-WindowsCapability -online -Name "<tool name>"
