It's official: Windows 7 is a hit

Last year at this time, Microsoft was in the final stages of preparing Windows 7 for its worldwide launch. The new OS was finally available to the public—well, at least that segment of the public with a TechNet or MSDN subscription. Those early adopters had to wait a few weeks after the official release to manufacturing date but still got a head start on the general public.

Those demanding and skeptical Windows users have now had a full year to stress-test Windows 7 and decide whether it’s good enough to replace Windows XP.

The verdict? Windows 7 has been a quiet success, maybe even a phenomenon. Last spring, a Microsoft executive told me that the company had sold 100 million Windows 7 licenses. As part of its quarterly earnings call in July, Microsoft announced that that number had risen to 175 million, and the company has projected that a total of 350 million Windows 7 licenses will have been sold by the end of this year. That’s a run rate of roughly 30 million copies per month worldwide, and it represents a lot of Windows 7-powered PCs.
