I'm having to rebuild (probably reinstall) my Win 10 VM that is currently SeaBIOS/i440 to UEFI/Q35. I want GPU passthrough, and from my understanding that won'y work on a legacy VM. What I am trying to find out , what does the Win 10 license anchor to? UUID? How can I rebuild or even reinstall as UEFI Win 10 VM without losing my license?
