I know that most people is using KMS to activate Windows Server 2012. I'm using it also with my own KMS server. But I also have lots of MSDN and Technet keys from my accounts. Before Windows Server 2012 I got MAK keys for Server. But with Server 2012 Microsoft only gave Retail keys. Have anybody tested out how many activations each Retail key have on Server 2012? Is it 10 online activations like Win7/Win8 Retail keys, or is it more, or less? Hope somebody knows.
