You most likely have an OEM version, very few people have the full version since it costs a heck of a lot more. The easiest way to tell what you have is to go into system properties and see what code is listed in the product ID section. The product ID looks like this. xxxxx-xxx-xxxxxxx-xxxxx You'll be concerned with what is listed in the group with only 3 digits, which is the second group. That tells you what you have. If OEM is listed then thats what you have. Here are the other codes available.
OEM - OEM SLP or OEM System Builder (MGAdiag will distinguish in the License Type field)
007 - VLK MAK
033 - VLK MAK
049 - VLK MAK
050 - Technet Plus Enterprise MAK (do same key used to activate Professional give this CID?)

If you are wanting to transfer that license to a new machine and stop using original pc then you'll need to upgrade the old pc to windows 10 then create an MS account and attach the activation to that account. Then install windows 10 on the new machine using the process MEP916 explained using the media creation tool and then log in using that same MS account you created for the first machine.
Follow this process to attach it to your ms account.
