It's true that Windows key is written in small print on the side of the tower; but I think that when there is a computer that is not the kind of thing that one takes account. He already has Windows I think it's good, three games including Tomb Raider sour it turns really well. It's true that by cons is bright and bruillant but this does not change that works great plus it's not too expensive for everyday players who want to run all the games that come out in the next final year I strongly advice I hesitated a long time on it because I did not know the make and I asked several questions which we answered me quickly. short I am satisfied with my purchase.
