Internet Explorer 10 (IE10) jumped into second place among Microsoft's browsers last month, pushing past IE9 through an enforced upgrade.
IE10's user share climbed from 16.5 percent to a record 24 percent of all copies of Internet Explorer in June, according to Web measurement firm Net Applications.
Among Microsoft's five supported browsers, IE10 was the second-most-used, leapfrogging the two-year-old IE9, which shed user share to end June with 20.9 percent of all copies of Internet Explorer. The 12-year-old IE6 was fourth with 10.9 percent, while 2009's IE8 remained in first with 40.4 percent.
IE10's climb has accelerated: June's user share increase was the largest since the browser's
introduction on Windows 7 in February. As in previous months, June's jump was fueled by the automatic update from IE9 to IE10 on Windows 7 that kicked in last winter.
Windows 8's
gradual if not dramatic rise in user share also contributed to IE10's increase, since that and Windows RT come with IE10: Windows 8's share grew in June by the largest amount since its
October 2012 launch.
