Assigning a single license of Windows Server Standard to a server permits you to run one instance of the software in one physical and one virtual OSE on that server. If you run both the permitted instances at the same time, the instance of the server software running in the physical OSE may only be used to run hardware virtualization software, provide hardware virtualization services or to run software to manage and service the OSEs on the server. To run more than two instances of Windows Server Standard on a server, you need to assign a Windows Server Standard license for each additional running instance in a virtual OSE, or, alternatively, assign a higher-level edition that permits more than one running instance in the virtual OSE at a time for example, Enterprise or Datacenter. You are permitted to assign as many licenses as needed to one server to license the number of running instances you require. You may run instances of prior versions of the server software instead of Windows Server Standard in any of the OSEs on the licensed server. You need a license for each instance running at the same time whether in a physical or virtual OSE.
