<s>[INST] The next text is a question of a member of the European parliament:"It is difficult for a consumer to purchase a PC or laptop that is not pre-loaded with the Microsoft Windows operating system. The seller tends not to give a breakdown of the price to allow the customer to see how much they are paying for Microsoft Windows, even though it is an addition to the basic machine.  Has the Commission investigated whether this is an unfair trading practice by Microsoft and companies selling hardware? Does the Commission believe that consumers should be able to buy a PC without an operating system, or at least know its cost and have the choice of choosing from a variety of different operating systems?"
