@Mario-Jakovina said in Windows 10 and RHEL 9 Dual Boot help.:
@Pete-S Any Windows 10 licence will technically work in VM, from my experience.
Yeah, but we're talking about the embedded license key that sits in the BIOS of the computer (when it comes with Windows OEM).
In a VM the guest can't access the BIOS of the host so it shouldn't be able to retrieve the embedded Microsoft licensing key. Unless the hypervisor makes it available to the guest.
The embedded licensing key is used automatically by the Windows installer and it will install Windows without asking the user for a key.
Back in the day there would be sticker on the bottom of the computer with the licensing key. But now it's stored in the BIOS somewhere and the sticker only has a windows logo on it.
