To make sure that Windows 7, Windows 8/8.1, Windows 10, and Windows Server clones are properly activated when the clones are created, you must use Microsoft volume activation on the parent virtual machine. The volume-activation technology requires a volume license key.
To activate Windows with volume activation, you use Key Management Service (KMS), which requires a KMS license key. See your Microsoft dealer to acquire a volume license key and configure volume activation.
Multiple Activation Key (MAK) licensing is not supported.
Before you create an instant-clone or View Composer linked-clone desktop pool, you must use volume activation to activate Windows on the parent virtual machine.
The following steps describe how activation takes place:
Invoke a script to remove the existing license.
Invoke a script that uses KMS licensing to activate Windows.
KMS treats each activated clone as a computer with a newly issued license.
If you set up a new KMS server and use QuickPrep to create linked-clone desktop pools, the KMS client count might not increment and the linked-clones might not be able to activate Windows. For more information, see the VMware Knowledge Base (KB) article http://kb.vmware.com/kb/2048742.
