But U.S. shoppers who pre-order between June 26th and July 11th will receive discounts of 50% or more, Microsoft said. For instance, Windows 7 Home Premium will sell for $49 during the discount period, while Windows 7 Professional will sell for $99. Participating retailers include Best Buy and Amazon, as well as Microsoft's own online store.
