Depende do método de ativação. Se você usar a ativação independente da MAK, ela não poderá ser revogada, se você usar a ativação do MAK Proxy, ela poderá ser revogada.
Isso ocorre porque uma ativação de Proxy requer acesso ao servidor VMAT da empresa pelo menos uma vez a cada 180 dias, e uma ativação Independente é independente do servidor VMAT.
There are two ways to activate computers by using a MAK:
MAK Independent activation. Each computer independently connects to and is activated by Microsoft either over the Internet or by telephone. MAK Independent activation is best suited to computers within an organization that do not maintain a connection to the corporate network.
MAK Proxy activation. MAK Proxy activation enables a centralized activation request on behalf of multiple computers with one connection to Microsoft. MAK Proxy activation is configured using the Volume Activation Management Tool (VAMT). MAK Proxy activation is appropriate for environments in which security concerns may restrict direct access to the Internet or the corporate network. It is also suited for development and test labs that lack this connectivity.
