Change Windows 10 from volume license (VLK Pro/Enterprise key) to use the key machines built-in key

Felt a bit stupid today (again). Have been struggling with some Microsoft Surface Go devices. Love the device but, when they are shipped with Windows 10 1803 version you will use some time updating them. So my brilliant idea was to reinstall them clean with the latest updated ISO from a stick. Smart right?, jupp except that I download the business VLK version.

Changing Windows product key (license) for a MDT OS deployment task

Creating a new OS deployment task in MDT you will be asked to specify product key

That’s easy enough, but what if you type in the wrong key or just want to change it (add it) later? You might even have gotten a new MAK.

That is not as easy, you cannot do it from the graphical interface, you have to do it from one of the configuration files. Well you might to it from graphical interface by typing it in every time deploying a computer gets deployed but that is not a great solution.
