100 million IE7 installations! 18 Jan 2007

"I'm pleased to report that on January 8th, we had the 100 millionth IE7 installation" says Microsoft Group Program Manager Tony Chor over at IEblog. "However, even more important than installations is usage. According to WebSideStory (the company we use to measure browser usage), as of this week, over 25% of all visitors to websites in the US were using IE7, making IE7 the second most used browser after IE6."

Microsoft expects these numbers to continue to rise as they complete their localised versions, scale up their roll-out via Windows XP's Automatic Updates feature, and launch Windows Vista on January 30, 2007 (with IE7 built in).

If you haven't checked your site in IE7 already, postpone all other work and do it now! Seriously!

(For examples of the glitches that IE7 introduces, take a look at our "IE7: Were they ready?" study from late last year. Our two Vitamin articles - "Internet Explorer 7: Were you ready?" and "Wake up and smell the IE7!" - should help you fix any problems you encounter).
