Microsoft is celebrating the first year anniversary of Windows 7 by doing a celebratory dance around the numbers - 240 million numbers to be exact.

“I think Windows 7 has exceeded expectations,” said Gavriella Schuster, the general manager of Windows Product Management.

The 240 million licenses sold makes up a 17% market share for the year-old OS, and 93% of new consumer PCs are running Windows 7, while 90% of companies have either made the transition, or are making it, to Windows 7.
