Weird MS Server 2016 Datacenter activation error & how to get around it

[NerdyDad]

We just paid our homage to those at Microsoft to use Windows Server 2016 Datacenter. We have our keys and are trying to activate. When I go to the GUI and attempt to activate with my key, I receive the following error:

However, after some googling and this site, I have found a workaround that activates the server. Open your command prompt under elevated privileges and run the following command

dism /online /set-edition:ServerStandard /productkey:<YourKeyHere> /accepteula

After a couple of minutes and a reboot, you're fully activated.
