Windows 8 may have 100 million licenses in the wild, but install base sits at an estimated 59 million

Microsoft may have sold 100 million licenses of Windows 8, but this doesn't mean that those licenses are all installed onto consumers' PCs. ComputerWorld talked with Patrick Moorhead, a principal analyst with Moor Insights & Strategy, who estimates that the actual number of Windows 8 devices being used is closer to 59 million.

This is according to the most recent data from Net Applications shows that Windows 8 is being used on around 4.2% of all Windows PCs. There are over 70 million PCs in the wild still running Windows Vista, which is a number that needs to change.
