View source for Unable to activate Server 2016 Standard License

==Purpose==
To activate Server 2016 Standard Evaluation with Server 2016 Standard Core activation key.

==Problem==
When entering the key into the GUI or using slmgr.vbs you receive an error stating the current edition of Windows can not be upgraded using the key.

==Solution==
To force Windows to change editions?<ref>https://social.technet.microsoft.com/Forums/en-US/5418a7cd-23d1-48c3-acbd-9300211e2508/upgrading-from-windows-server-2016-standard-quotevaluationquot-to-a-fully-registered-version?forum=ws2016</ref> According to what I found online, I had to force tell Windows what edition to change to before it would take the key I provided. Running
<pre>
dism /online /get-targeteditions
</pre>
gave me the output showing ServerStandard, which is what I should be able to use my key with. In order to get it to take I needed to run
<pre>
dism /online /set-edition:serverstandard /accepteula /productkey:xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
</pre>
At this point the system reports it is removing the Server Standard EvalEdition package. It sits at 10% for a very long time, just have patience. This is a Microsoft product after all.
