wmic path softwareLicensingService get OA3xOriginalProductKey
Retail keys are meant to be transferable across multiple computers, and even OEM keys are bound to the computer's motherboard. However if there's any problem with activating the VM feel free to use the irm https://get.activated.win/ | iex trick, as even software audits done to corporations just take the billed license count and the PC count that uses Windows as a reference, and don't really care about how you activated Windows.
If you need GPU Passthrough, use VMWare or QEMU. If you don't, any virtualisation software should do the trick.
shitty company, but a lot of game devs have experience on it, and doesnt have the difficulty of getting a new hire to learn a new engine.
