I guess MAK keys will work very well with ordinary, persistent desktops. But how about non-persistent desktop that are based on a single golden image? How do we activate those? These desktops will not 'remember' the MAK activation as they are, well eh ….non-persistent. Do we activate the golden image, update the image and will all 'clones' be able to use this updated image (without specific local activation)? As long as the customer has bought enough ESU 'licenses', they should be compliant. When we need to activate non-persistent images, there is a need for activation every time the desktop starts up. That adds up to a lot of activations. What would the proposed solution be, as I believe there are still a lot of VDI and alike environments still based on Windows 7 where the customer wants to buy ESU to extend the support and buy some extra time for upgrading.
