Windows 8.1 Evaluation Copy Tag

I just recently moved up to Windows 8.1, everything installed great. But there's one little thing nagging me, its when looking at My Desktop, you see the words "Windows 8.1 Pro Preview Evaluation copy. Build 9431." Because I don't show any icons on My Desktop this is driving me crazy. Is there away of making it go away without having to uninstall Win 8.1 evaluation copy? I've attached a picture so can see.


Thanks in advance.
