I am currently running Win 7 Home Premium 64-bit. I am considering upgrading to Win 7 Ultimate, as I can get that for around $10.00 from where i work. What happens to licensing for ZBrush? Will ZBrush continue to work, or will I have to de-activate and re-activate?
You would probably be OK. But to be on the safe side I would recommend Web Deactivation before upgrading. It’s only a couple minutes’ effort and can save headaches later.
