Report: IE 9 Hits 12 Percent Usage on Windows 7 Machines

According to NetMarketShare, a Web tracking and analytics service provided by Net Applications, Microsoft's latest version of Internet Explorer finished off May with 12.0 percent of the worldwide browser market.

The numbers are slightly better on Windows 7 machines, with 12.2 percent of global usage. Roger Capriotti, director for Microsoft's Internet Explorer product marketing team, commented in a blog post that the May worldwide market share number represents an increase of 60 percent over April's figure.

Capriotti noted an even stronger finish for IE 9 on Windows 7 in the U.S. market, saying that "in the US, IE9 has now passed 17 percent usage share on Windows 7 as of the last few days in May."

While the increases are good news for Microsoft's newest browser and operating system, IE 9 isn't showing the kind of growth that Google's latest Web browser has demonstrated, according to Net Applications' May data. Google Chrome 11 edged out IE 9 with 14.8 percent of the market. In addition, Chrome 11 had a month-over-month growth increase of 6.9 percent, according to Net Applications' May data. IE 9 is still a relatively new entrant, though, having been released in March.

If all operating systems are considered, IE 9's numbers aren't as strong, with just a 4.2 percent market share. IE 9 is limited to only running on Windows 7- and Windows Vista-based machines. While the numbers show a growth of 0.9 percent over the previous month, IE 9 has a lot of catching up to do to the market leader, Microsoft's own Internet Explorer 8, which continues to head the pack with 31.3 percent use.

Internet Explorer 6 finished second, with10.4 percent of the global browser market, while Mozilla's FireFox 4 finished up in third place with a 10.0 percent share.

so, this car is double the cost of a pilot, its lgraer, bloatier, and has some of the most unreliable tech ive ever seen in my life. for 44K dollars and 24 MPGwith a 3rd row as a joke its no wonder the pilot made car of the year in this department. ive spoken to several of these new explorer owners and theyre very unhappy with them. and i can see why. the pilot handles and drives like an accord v6, its nimble and feels small. this, well,its fast but theres zero steering or cornering or even park [url=]wnmdhsk[/url] [link=]gsmhlnro[/link]

sometimes a template is not meant for both ffreiox and IE. If u really like this template, why don't u make a sticky post saying that your site is best viewed using ffreiox?

IE9 will not work properly with Citrix Web Logins for medical billing, nor with the Automotive Supplier login sites. Some of them will function, while others will not. This lends to Java issues as well. - Had to uninstall IE9 from Win 7 PC through the updates, not in Programs menu.
