Licenciamento por Volume
O Windows 7 Enterprise só está disponível por meio do canal de Licenciamento por Volume (VL). Ao contrário das outras edições que estão disponíveis em OEM ou canais de varejo, uma única chave pode ser usada para várias ativações.
With Volume Licensing for products such as Windows 8.1, Windows Server 2012 R2, Windows Server 2012 R2 for Embedded Systems, Windows 7, Windows Server 2008 R2, Windows Vista, Windows Server 2008, Microsoft Office 2010, and Office 2013, you must use Volume Activation (VA). To activate these products with VA, you can use either a Multiple Activation Key (MAK) or Key Management Service (KMS).

MAK
A MAK is used for one-time activation with Microsoft's hosted activation services. Each MAK has a predetermined number of allowed activations; this number is based on Volume Licensing agreements and does not match the organization's exact license count.

KMS
Through KMS, organizations set up a local KMS host (or hosts) that connect once to Microsoft to activate the KMS host(s). Then the individual systems throughout the organization connect to the KMS host(s) and activate transparently.
With KMS, client computers connect to the local KMS host to activate the first time, then they reconnect periodically to keep the activation current. KMS is capable of activating an unlimited number of computers, so it can be used for a VL agreement of any size.
