2011-02-04
By Jan 27, 2011, Windows 7 sold 300 million licenses.
To put that in perspective, 300 million is roughly the combined number of households in North American and in Europe! Or, to put it another way, if you lined up 300 million Windows 7 product boxes, they would stretch nearly 1.5 times around the Earth!
As of today, over 20% of Internet-connected PCs worldwide are running Windows 7 according to Net Applications.
