Automatically download Enablement Packages

Happy New Years everyone! I was recently reading a blog post by Gary Blok that explained how to upgrade to Windows 10 21H2 via Enablement Package using the ConfigMgr App Model. It is a great article and I actually plan on using an Enablement Package to upgrade all of my 20H2 PC’s to 21H2. However, due to my anxiety I didn’t like that I actually had to setup an ADR to download the Enablement Package. So instead of using an ADR, I wanted to see if I could accomplish this with the ConfigMgr Powershell CMDLETs. Fortunately with ConfigMgr 2107, Microsoft released a new CMDLET Get-CMSoftwareUpdateContentInfo that can help us easily retrieve the source path for the Enablement Package .cab files. All you need to make this work is a site with 2107 installed, ConfigMgr console installed on the device that you are running the script, Powershell 3.0 and above, and the following Products and Classifications:

Product: Windows 10

Classification: Upgrades

Powershell Script:

$DownloadFolder = "$env:TEMP\Enablement Packages"

If(!(Test-Path "$DownloadFolder")) { New-Item "$DownloadFolder" -ItemType Directory -Force }

Get-CMSoftwareUpdate -Fast | Where-Object { $_.LocalizedDisplayName -like "*Enablement Package" } | ForEach-Object {

    $SourceURL = (Get-CMSoftwareUpdateContentInfo -Id $_.CI_ID).SourceURL
    $LocalizedDisplayName = $_.LocalizedDisplayName -replace '(?= via Enablement Package).*',''

    If(!(Test-Path "$DownloadFolder\$LocalizedDisplayName")) { New-Item "$DownloadFolder\$LocalizedDisplayName" -ItemType Directory -Force }
    Invoke-WebRequest -Uri $SourceURL -OutFile "$DownloadFolder\$LocalizedDisplayName\$(($SourceURL -replace '.*([/])','').Split('_')[0]).cab"

}

Start $DownloadFolder
