As I described earlier I had an eval image in my marketplace that I used to provision servers and I wanted some of them to be converted so they could be correctly activated and reconfigured away from eval.

The AzureStack uses the function within Hyper-V for the VM´s that is called Automatic Virtual Machine Activation and as you can see in the device manager the device Microsoft Hyper-V Activation Component and the VM´s should have the appropriate AVMA key on them and if the host is licensed with the right key the VM will activate automatically.

On this page you can find the keys you need for the different guest-OS that it can be used with!  A Windows Server 2016 AVMA host can activate guests that run the Datacenter, Standard or Essentials editions of Windows Server 2016 and Windows Server 2012 R2.

Utilizing the DISM command I can check what license I had and then use DISM /online /Set-Edition:ServerDatacenter /ProductKey:xxxxxx-xxxx-xxxx-xxx-xxxx /AcceptEula

If you just want to change a key and not versions you can utilize the slmgr /ipk <AVMA_key> instead of the DISM!
