A friend of the family bought a new PC last year, I think someone they new built it for them. It has now come to light that the version of XP they have installed is not licensed; they found this out when Windows tried to update. They are in a bit of a tizz about it (what with being of the older generation and not knowing much about PCs) and want me to sort it out for them. Now I'm wondering what the best way is to resolve it. I don't want to have to buy a copy of Vista and install it on their PC so was hoping that MS would sell a licence key and then validate the current version of XP. Does anyone know if they will do that or what the options are??
