Every time we get a situation like this in our shop, we always try our best to sell a Genuine OS to the cliente and explain that the Genuine Windows version solves a lot of bugs due to the Windows updates and spares a lot of headaches, and they do end up buying it because 90% of clientes didn’t even know that there software wasn’t the real deal. But now and again we do get a few that will not even consider it because of economical reasons and we are not one to judge, so best we can do is a temporary fix.
