Microsoft this evening hit a record high $16.2 billion in revenue for its summer quarter. The figure was a 25 percent jump from a year ago and was helped by unfettered Windows 7 sales as well as Office 2010 and the Xbox 360. It wouldn't quote numbers but sold 38 percent more game consoles than it did last summer, owing largely to the slim Xbox; the console has been in the sales lead for four months.
