I’ve got a few easy links for you to visit if you haven’t had a chance to check out Windows Server 2012 R2 or Hyper-V 2012 R2. I’ve also included a few other links of interest as well!

If you haven’t gotten an Azure trial yet, you can find that here – http://aka.ms/NewAzureTrial and for some extra learning, check out the Microsoft Virtual Academy.
Need something else? There is always the TechNet Evaluation Center. The Windows 8.1 Enterprise Evaluation is available there now.
