Windows 8 sold 100 million times but installed only 59 million?

Although Microsoft recently touted having sold 100 million Windows 8 licenses this week, careful observers noted that selling all those licenses doesn’t mean vendors have actually sold 100 million Windows 8 devices over the past half-year. ComputerWorld this week talked with Patrick Moorhead, a principal analyst with Moor Insights & Strategy, who estimates that the actual number of Windows 8 devices being used out in the wild is closer to 59 million, since the most recent data from Net Applications shows that Windows 8 is being used on around 4.2% of all Windows PCs.
