I think I finally got what you meant.
On a physical Machine, you can upgrade windows 7 to windows 10 on a physical machine and it will activate. You can wipe the hard drive and do a clean install of 10 on a physical machine skipping entering the keys and physical machine will activate.
Instead of creating a new virtual machine, you wipe the virtual hard drive, then do a clean install of windows 10 and the virtual machine should activate. If you create a new virtual machine it considered a new computer even though it has all the same emulated hardware.
