My PC motherboard just died, with what I believe was an OEM Windows 10 licence on it. I want to migrate the drives and ideally the whole Windows 10 setup (including apps and settings) to my new machine, which will also have an OEM Windows 10 Licence on it. I believe that if I simply plug the old Windows boot drive into the new machine/motherboard it will allow me to run a restricted/unactivated version of Windows 10, but is there any way that I can use my new OEM key to re-activate the system, so that I can pick up where I left off? Or am I stuck with having to re-install everything from scratch? I also have a Macrium Reflect image backup of my boot drive, if that helps in any way??
