Windows 10: Reuse the device product key in unattended install

I am trying to automate the reinstall of Windows 10 computer at work (if only to get rid of all the bloatware that is added by manufacturers).


I have created an unautoattended.xml file following this tutorial:

https://www.windowscentral.com/how-create-unattended-media-do-automated-installation-windows-10


With one difference: my machines were shipped with valid Windows 10 Pro licenses, and I would like the unautoattend to reuse those licences. I do not want to have to re-generate the xml file with a different product key every time I reinstall Windows 10.


I tried to just not specify the Product Key in the unautoattend.xml, but the Setup fails, saying it cant read the value. It doesn't even prompt for one.


How can I do that ?


Regards

:)

Window 10 Product Key Reuse

Hi. I need to replace the hard drive of my laptop so I will have to do a clean Windows 10 installation from a fresh HDD.

QUESTIONS:

1. Can I reuse my Window 10 product key?

2. Where can I see the Window 10 product key?

Also, my workstation is originally a Window 8.1 machine meaning I'am using a upgraded Window 10 version.

Hej Ken. Din svarfil antyder att du är också en Finlandsvensk. Välkommen till Ten Forums!






Hi Ken. Your answer file suggests that you are a fellow Finland Swede. Welcome to Ten Forums!

That error is because there's no generic product key or MAK key in your answer file. It is obligatory in autounattend.xml answer file, the one that takes care of first phase of Windows setup, partitioning and installing.

Please see step 3.9 in following tutorial for how to add key in answer file: Create media for automated unattended install of Windows 10
