Trying to make Server 2016 Tp3 available to some admins here for testing/playing.  I cuild a VM from the 2016TP3 ISO and when I sysprep and then deploy, the deployment requires a product key.  No idea how to sysprep and avoid this, and I can't find a product key for 2016 (I know it probably doesn't exist).  Any ideas around this?

Hi Baum,

I'm afraid I could find related information of product key.

However, according to the installation guide: Upon installation, you will be prompted to activate. A product key is not required for the ISO installation.

Here is the reference:
