Upgrading WIndows Server 2012 R2 eval media to fully licensed

Open an elevated command prompt.
Type slmgr.vbs /div and you should see "EVAL" indicating your current installation is for evaluation only.
Type dism /online /get-currentedition and note the edition ID.
Type dism /online /set-edition: /productkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX using your previously determined edition ID and your MAK license key.
