Microsoft's planned retail store openings will start just in time for Windows 7's appearance next week, a leak late yesterday may reveal. A single source for the WSJ says the first store, in Scottsdale, Arizona, should open either on Windows 7's October 22nd release date or within a few days afterwards. However, it would be the only store to launch near the OS as the Mission Viejo, California store would only open a few weeks later.
