No. In a Microsoft environment when a KMS server responds to an activation request from a qualified product, it issues an activation ID. This ID corresponds to the software package and will be the same for every product in the environment. What I mean by that is that all Office Professional 2010 installs will have the same activation ID for each system requesting activation. It'll be the same for Windows 7 Professional, Windows 7 Enterprise and so on. Each seperate software package will receive a different ID, but each install of the package will have the same ID.
