Retail, OEM and Volume Licences Explained
Retail licences
A Retail licence is sold directly to an end user. It is usually tied to one person or device at a time and can normally be moved to a new computer if you remove it from the old one first.
OEM licences
An OEM (Original Equipment Manufacturer) licence comes with, or is installed on, a specific computer. It is meant to stay with that hardware for its whole life and usually cannot be transferred to another machine.
Volume licences
Volume licences are designed for organisations that need many installations. They are managed centrally by IT and often use activation methods such as KMS or MAK.
