Windows OS Market Share

 

October 2009 OS stats: Windows 7 passes Snow Leopard, Linux

Bar Graph: Worldwide OS share by version of Windows and Mac OS X

Pie Chart: OS Share among Ars Technica readers

At this point in time, Windows continues to dominate with more than 90 percent of the market, Mac OS is above the five percent mark, and Linux is just under one percent. In October, Windows was the only operating system not to show positive growth.

Between October and September, Windows dropped 0.25 percentage points (from 92.77 percent to 92.52 percent), Mac OS climbed up a sizeable 0.15 percentage points (from 5.12 percent to 5.27 percent), and Linux edged forward 0.01 percentage points (from 0.95 percent to 0.96 percent). Windows' drop is worth noting given that it occurred in the month that Windows 7 was released, but November may show something different given that it will be a full month of sales of the operating system. Still, Windows 7 did quite well; it managed to pass Linux, Snow Leopard, and even both of their shares combined (2.13 percent versus Windows 7's 2.15 percent)
