Install RSAT Tools on Windows 10

I've written a short script to download and install the RSAT tools for Windows 10. This script works on the recent versions of Windows  10 only! Here goes:

# 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*'
