As part of the advertising campaign for Windows 7 in Japan, Microsoft has partnered with Burger King. The result of this partnership is a Whopper with, you guessed it, 7 burger patties. The Windows 7 Whopper will cost 777 yen, and will be available for 7 days. However, this price is only good for the first 30 customers each day. Customers after that will find themselves paying roughly double that price. I'm surprised that Microsoft didn't consider launching this promotion in America, where fast food is extremely popular.
