I haven't actually tried it, but my understanding is that it gets a bit murky if you bought the System Builder version of Windows vs. the retail one. The System Builder version is tied to the hardware of one machine and cannot be transferred (nor the computer made substantially different, hardware-wise) whereas the retail version can.

I bought the System Builder version to save money when using Boot Camp, but I have yet to try installing that same copy in a VM.

Can you install the same Windows license virtually to the same machine it previously had a partition for?

Yes, you can install it, but it Activation will fail unless it's a Retail version of Windows.

Virtual Machines appear to Windows as different hardware than the underlying system the Virtual Machine is running on. Think about what is necessary for a Virtual Machine to function. All communication directed at hardware is intercepted by the Virtual Machine software and an "expected" response is generated. For example: If Windows asks "What hardware am I running on?" the Virtual Machine will respond with "A Virtual Machine" whereas if the same question was asked by Windows running directly on hardware, the response would be information about that hardware.

When installing Windows on a Virtual Machine, the activation process thinks it's a totally new machine. Retail Windows allows transferring to new hardware. OEM Windows does NOT. Of course, the license agreement requires you to remove the previous copy of Windows: Windows' (Non Enterprise) licences are only good for ONE computer.

Cheers, PW.

P.S. You don't really need to remove the previous copy of Windows. All that's required is its activation must be disabled. The command to do this. . .

The command means "System Licence Manager Uninstall Product Key"
