Microsoft have basically charged me a £220 tax for fixing my PC. My PC was gifted to me by my old employers, complete with a windows 7 install, which was upgraded to windows 10.My motherboard blew, so I had to replace it. As a consequence, Microsoft *require* a product key, which I don't have, because my PC was a gift. So a version of windows that was activated, no problems, is now toast, and Microsoft say I need to buy a new one!It's outright fraud!
