Windows 7 has surpassed XP as the most widely used operating system in the world according to new data from StatCounter. The operating system now has a 40.21% usage share of the global desktop OS market, compared to Windows XP, which has a 38.64% market share. Windows XP is trailed by Mac OS X and Linux. Microsoft first released Windows 7 in October of 2009, and its versatility and ability to run on everything from low-powered netbooks that were typically powered by Windows XP, to high-powered desktops and business machines has no doubt contributed to its success. Microsoft will release its next operating system, currently dubbed Windows 8, in late 2012.
