Windows 10 20H2 RSAT tools are failing to install from FOD

[lalajee]

Hi,

I'm trying to install RSAT tools on Windows 10 20H2 but it keep failing

Step I use to install.
I download the FOD from Microsoft site "Windows 10 2004 FOD" which is also for 20H2
Then run this script to extract the files 

$FoD_Source = "C:\Downloads\W10RSAT_FOD\2004\2004_FoD_Disk.iso"
    
 Mount-DiskImage -ImagePath "$FoD_Source"
    
 $path = (Get-DiskImage "$FoD_Source" | Get-Volume).DriveLetter
    
 $lang = "en-US"
    
    
    
 $dest = New-Item -ItemType Directory -Path "$env:SystemDrive\temp\RSAT_2004_$lang" -force
    
    
 Get-ChildItem ($path+":\") -name -recurse -include *~amd64~~.cab,*~wow64~~.cab,*~amd64~$lang~.cab,*~wow64~$lang~.cab -exclude *languagefeatures*,*Holographic*,*NetFx3*,*OpenSSH*,*Msix* |
 ForEach-Object {copy-item -Path ($path+“:\”+$_) -Destination $dest.FullName -Force -Container}
    
 #get metadata
    
 copy-item ($path+":\metadata") -Destination $dest.FullName -Recurse
    
 copy-item ($path +“:\"+“FoDMetadata_Client.cab”) -Destination $dest.FullName -Force -Container
    
 #Dismount ISO
    
 Dismount-DiskImage -ImagePath "$FOD_Source"

 

Then use this script to install the RSAT tools 

 $FoD_Source = "$env:SystemDrive\temp\RSAT_2004_en_US"
    
 $RSAT_FoD = Get-WindowsCapability –Online | Where-Object Name -like 'RSAT*'
    
 #Install RSAT Tools
 Foreach ($RSAT_FoD_Item in $RSAT_FoD)
 {
     Add-WindowsCapability -Online -Name $RSAT_FoD_Item.name -Source $FoD_Source -LimitAccess
 }

but i get this error message

We have WU blocked as all patching is handled by MEMCM.  I found this workaround script to temporarily enable in the registry, add the feature, then set the registry back to what is was prior.

 

$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
