April 9, 20179 yr I am speaking from the procedure of upgrading your windows 7 license to 10. If I recreate the VM from scratch, how do I retain the windows 10 license working? Sent from my LG-D855 using Tapatalk
April 9, 20179 yr So Windows 10 is tied to hardware, once you install it the key is tied to the motherboard and you never have to re enter it no matter how many times you reinstall Windows 10 on the same hardware. Change the hardware and you have to re register the key. Now if you have a Windows 7, 8, 8.1 key you can use these when registering a fresh install of Windows 10 and it will work. As far as virtualization goes, you are required to have a unique license for every virtual machine you run. So if you are running Windows 10 on your physical desktop, setup an unRAID server and decide you would like to try and build a Windows 10 VM, you can't use the same license you have for your physical desktop, you are required to buy a new separate license for your VM, this goes for any Microsoft VM's you setup.
April 9, 20179 yr Author Yes, understood that unique windows license per instance. My concern now though is up to when will Microsoft allow Windows 7 serial number to be used to activate Windows 10? It may very well stop next month. So my concern is, assuming i want to make sure my VM has a proper license now, and everytime I reinstall, is there a way to extract windows 10 license provided, and reuse next time I recreate the VM?

April 9, 20179 yr I think I remember someone on the forums here saying activation follows the UUID of the VM, so as long as you keep the same UUID you should be good. Don't take this info for gospel until you verify it though, it's just my foggy recollection.
April 9, 20179 yr No one has a crystal ball and and can answer your question they may stop next week, next month, next year who knows. However if Microsoft wants to move as many people from Windows 7 and 8 to Windows 10, they will keep on allowing it for a long time.
April 10, 20179 yr Author Thanks ashman70, Jonathanm, how do you retain UUID after reinstallation? Sent from my LG-D855 using Tapatalk
