You can also get Office or other Microsoft software with OEM licenses if you buy them bundled with a computer or server. When you buy a computer or server and you get Windows or Windows Server pre-installed, you are getting an OEM license.

OEM licenses are only available included with the purchase of hardware.The four most common license types for Microsoft software are OEM, Retail, Volume, and Subscription. Not necessarily related to the version or edition, there are several license types. The different flavors of one version, like 2012 R2 Standard, Datacenter, Essentials, or Foundation, are called "Editions" by Microsoft. The different generations of Windows Server, like 2003, 2008, 2012, are called "Versions" by Microsoft.
