Installing RSAT tools

I've been installing 1803 (and for reasons I can not explain, 1709)  on a bunch of workstations - but needed the RSAT tools. I HATE having to use the GUI - so here's a PowerShell script:

# Install-RSATTools.PS1 # Thomas Lee - doctordns@gmail.com # 1. Get Windows Client Version and Hardware platform $Key = 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion' $CliVer = (Get-ItemProperty -Path $Key).ReleaseId $Platform = $ENV:PROCESSOR_ARCHITECTURE "Windows Client Version : $CliVer" "Hardware Platform : $Platform" # 2. Create URL for download file # NB: only works with 1709 and 1803. $LP1 = 'https://download.microsoft.com/download/1/D/8/'+ '1D8B5022-5477-4B9A-8104-6A71FF9D98AB/' $Lp180364 = 'WindowsTH-RSAT_WS_1803-x64.msu' $Lp170964 = 'WindowsTH-RSAT_WS_1709-x64.msu' $Lp180332 = 'WindowsTH-RSAT_WS_1803-x86.msu' $Lp170932 = 'WindowsTH-RSAT_WS_1709-x86.msu' If ($CliVer -eq 1803 -and $Platform -eq 'AMD64') { $DLPath = $Lp1 + $lp180364} ELSEIf ($CliVer -eq 1709 -and $Platform -eq 'AMD64') { $DLPath = $Lp1 + $lp170964} ElseIf ($CliVer -eq 1803 -and $Platform -eq 'X86') { $DLPath = $Lp1 + $lp180332} ElseIf ($CliVer -eq 1709 -and $platform -eq 'x86') { $DLPath = $Lp1 + $lp170932} Else {"Version $cliver - unknown"; return} # 3. Display the download details "RSAT MSU file to be downloaded:" $DLPath # 4. Use BITS to download the file $DLFile = 'C:\foo\Rsat.msu' Start-BitsTransfer -Source $DLPath -Destination $DLFile # 5. Check Authenticode signature $Authenticatefile = Get-AuthenticodeSignature $DLFile If ($Authenticatefile.status -NE "Valid") {'File downloaded fails Authenticode check'} Else {'Downloaded file passes Authenticode check'} # 6. Install the RSAT tools $WusaArguments = $DLFile + " /quiet" 'Installing RSAT for Windows 10 - Please Wait...' $Path = 'C:\Windows\System32\wusa.exe' Start-Process -FilePath $Path -ArgumentList $WusaArguments -Wait # 7. Get RSAT Modules Get-Module -Listavailable | Where-Object Name -like '*rsat*'
