StatCounter has issued its latest operating system marketshare data. In the data below you can see the most widely used desktop operating systems in February 2015. Windows 7 still reigns supreme with a marketshare of 54.13 percent, down from 54.67 percent in January, whereas the combined marketshare of Windows 8 and Windows 8.1 rose from 18.59 percent to 18.91 percent in the same timeframe.
Surprisingly, Windows XP's marketshare rose from 11.99 percent to 12.23 percent. Despite no longer receiving security updates since April 8, 2014, quite a number of people are still counting on XP.
Apple's OS X accounted for 9.09 percent in February, pretty much the same as January's 9.10 percent. Windows Vista's marketshare dropped from 2.69 percent to 2.53 percent while all Linux distros combined saw their total marketshare rise from 1.46 percent to 1.55 percent.
