Which activation method should be used for virtual computers?

Either MAK or KMS may be used to activate virtual computers. KMS is the preferred method because activations are not decremented each time a computer is activated (as is the case when using MAK). This applies to both physical and virtual computers.

Consider the following when activating Windows and Office on virtual machines:

  • Windows Vista SP2, Windows Server 2008 SP2, Windows 7, Windows Server 2008 R2, and Office 2010 count toward KMS activation thresholds.
  • Windows Vista SP1, Windows Server 2008, Windows Server 2003 v1.1, and Windows 7 support hosting KMS on a virtual computer.
  • Each KMS Host Key can be used to set up six KMS hosts (physical or virtual).
