Microsoft announced Friday it has hit the 100 million installation milestone for Internet Explorer 7, a figure that makes the new browser the second most used behind IE6. Web analytics firm WebSideStory reports that 25 percent of all Web surfers in the United States are now running IE7.
“We expect these numbers to continue to rise as we complete our final localized versions, scale up AU distribution, and with the consumer availability of Windows Vista on January 30, 2007,” wrote IE group program manager Tony Chor on the IEBlog. Because IE7 is built into Windows Vista, Microsoft expects adoption rates to jump further as consumers upgrade. Already, Microsoft is preparing to discuss the next version of Internet Explorer at the company’s MIX conference that begins April 30.
