WinXp is Still Alive

Windows XP continues its descent among desktop operating systems, though it's far from dead and buried.

Looking at the overall Web traffic for desktop operating systems across the globe, Net Applications gave XP a 16.9 percent share for the month of March, a hefty drop from the 19.1 percent recorded in February.

Though XP's grip on the market continues to loosen, it remains the No. 2 most-used operating system based on Net Application's Web stats, beating Windows 8 and 8.1 and their collective share of 14 percent. Windows 8.1 took the third spot with a 10.5 percent share, leaving Windows 8 in fifth place with just 3.5 percent.

Windows 7 holds the top spot, with a share of 58 percent.

The enduring hold of the 13-year-old Windows XP on PC users underscores the challenges Microsoft has faced as it tries to move ahead with new versions of its flagship operating system, which the company says has more than 1.5 billion users around the world. The staying power has even proven resistant to Microsoft's end of support for XP a year ago, which put an end to bug fixes and and other patches, leaving users more vulnerable to security threats.
