Net Applications reports that global usage of Microsoft 's venerable Windows XP operating system has declined 11 percentage points since February of last year. According to the Web metrics firm's latest data , Windows XP held a 46.52 percent share of the online PC market at the end of 2011.
The majority of users who upgraded from XP last year are now running Windows 7 on their desktop PCs, notebooks and netbooks. Windows 7 accounted for 37 percent of global market share at the end of December -- a rise of 13 percentage points from February 2011.
Net Applications Executive Vice President Vince Vizzaccaro believes XP's declining percentage is great to see. However, he noted that the change is probably not happening fast enough from the point of view of Microsoft's own efforts to upgrade Internet Explorer as well as software developers committed to the latest HTML5-compatible application designs.
"I do believe Microsoft's strategy to focus their browser efforts on the more advanced operating systems has merit," Vizzaccaro said. "It could be argued that anyone still using XP is more likely to continue to use IE6, even if the latest IE versions were made available for XP."
The Netbook Factor
One reason for the steady decline in Windows XP's market share is falling netbook unit sales, many of which had shipped with Windows XP. According to DisplaySearch, netbooks accounted for approximately 20 percent of all laptop shipments worldwide from the fourth quarter of 2008 through the second quarter of 2010.
Following the successful launch of Apple's first iPad in the first half of 2010, however, mini-notebook sales began to slip. By the first quarter of 2011, mini-notebook shipments had declined by 12.2 percent year over year, according to Gartner .
Still, the 37 percent market share reported by Net Applications falls short of Gartner's prediction last August that Windows 7 would be running on nearly 635 million new PCs worldwide by the end of 2011 -- equivalent to a global market share of 42 percent. Though many enterprises have moved rapidly to embrace Windows 7, a significant number of consumers are reluctant to abandon XP. (continued...)
