Microsoft’s Windows 7 operating system overtook its 10 year old sibling XP globally for the first time in October, according to StatCounter. The firm’s research arm StatCounter Global Stats reports that in October Windows 7 took 40.5% of global web market share with XP at 38.5%. Windows Vista, which was intended to replace XP, is down at 11.2% globally. The fact that it has taken this long for Microsoft to put out an OS that could supplant Windows XP really says something about the quality and overall reliability of that platform. I think that Windows 7 will be the OS that ultimately brings those last set of holdeovers into the fold.
The StatCounter analysis finds that Windows 7 overtook XP in the United States in April of this year and in Europe in July. However, in Asia Windows XP still retains a clear lead at 55% in October compared to 36% for Windows 7. Vista in Asia is at 5%.
