I have a feeling it might be Enterprise. She had a second laptop from the same company which I helped her restore earlier today and its just up and running now and its Enterprise. I would hazard a guess that if that one is this one will be also. She doesnt need Enterprise of course. Its just going to be for her use at home now but presumably that is the only version that would be licenced for that machine? You couldnt stick W10 Pro on unless you had a key?
