When rebuilding your windows 10 desktop that hold a digital license key there is no piece of paper that tells you the activation key.

with the following command you can read the product key

$service = get-wmiObject -query ‘select * from SoftwareLicensingService’

$service.OA3xOriginalProductKey

$key=$service.OA3xOriginalProductKey

this is handy for getting the key but when you are deploying a WDS image and everything needs to be unattended you will need a little PowerShell script

As an option there to place a different key for if you are in a mixed environment.

$service = get-wmiObject -query ‘select * from SoftwareLicensingService’

$service.OA3xOriginalProductKey

$key=$service.OA3xOriginalProductKey

$service.InstallProductKey($key)

$service = get-wmiObject -query ‘select * from SoftwareLicensingService’

if($key = $service.OA3xOriginalProductKey){

Write-Host ‘Activating using product Key:’ $service.OA3xOriginalProductKey

$service.InstallProductKey($key)

}else{

#Write-Host ‘Key not found., use a different license’

# $service.InstallProductKey(‘Put your License KEY here’)

}

Save this as a Powershell script and put this in the unattended.xml and when deploying the Windows 10 will be auto activated

Get the script from the site or from the TechNet gallery.
