Windows 7 is now the world’s most popular desktop operating system, according to the August report from Net Applications.

In August, Windows 7 had a 42.76% market share, a fraction of a point more than Windows XP’s 42.52%. Windows Vista sits at third place with a 6.15% market share, followed by Mac OS X 10.7 and Mac OS X 10.6 with 2.45% and 2.38%, respectively.

All in all, older versions included, Microsoft controls some 92% of the market. It took three years for Windows 7 to become the world’s most popular OS. Microsoft’s desktop operating system, which was launched in October 2009, will soon be replaced by a newer version — Windows 8.
