How to Deploy Windows 10 with a OEM ProductKey from the BIOS with Microsoft Deployment Toolkit

For a customer I had to adjust their Microsoft Deployment toolkit installation to use the OEM Product Key from the BIOS instead of a general Volume Licensing key.

If you want to get the Productkey from the BIOS you can do this with the following Powershell commands:

Software Licensing Service WMI Class information:

Please be aware that by default this class is only available in a Full Windows OS.

Powershell Script:

$Productkey = (Get-WmiObject -Class SoftwareLicensingService).OA3xOriginalProductkey



This will give the 5X5 Productkey as a result.

This can be used with Powershell to input into the Software Licensing Manager tool (SLMGR.vbs) with the /ipk option.

iex "cscript /b C:\Windows\System32\slmgr.vbs -ipk $Productkey"


iex "cscript /b C:\Windows\System32\slmgr.vbs -ato"

Now you can use this script within MDT as well.


Download the PowerShell script and save it to your %DeploymentShare%\Scripts folder

Add a new 'Run PowerShell Script' step to your Task Sequence and configure it with the settings below:


Happy Deploying,...

    Great, thank you very much. I tried bat/cmd/vbs but had trouble with it. This powershell script worked flawlessly.
    Exactly what i was looking for.

    Hello, I have been using this since january. With OEM 8/8.1/10 key. Works great. Now I have implemented Win10-1703 and no go anymore. For as far as I know the invoke expression and the slmgr still work the same. Could you help me with this. Thanks in advance.

    Where in the task sequence would you put this?

      In the full Windows OS part of the Task Sequence.

        i cannot seem to find that task sequences part… do you mean under Install – Install OS? i cannot seem to get this to work. is there anyway of getting it to ignore having to enter a key during install and have the script run once the OS is installed? thanks!

    Hi. Thanks for the powershell script. It’s working as the windows gets activated with the OEM product key. But at the end of the deployment i do get an error. The ZTIPowershell.log shows the below. How can I resolve this issue ?
