While upgrading a ProWMC Win 8 to the preview and build 9471 it worked. For clean install it has to be proved.
I've got a license for Windows 8 Pro for two years from Microsoft Dreamspark so if i install Windows 8.1 Pro in clean install and i add that license number will be activated ?
Does this mean that the Preview build did not use KMS v6? Because I definitely used KMS to activate the preview.
