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)? 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 ESU to extend the support and buy some extra time for upgrading.
