Internet Explorer 9 will NOT support Windows XP!

Yesterday, Microsoft made a first developer preview of Internet Explorer (IE) 9 available for download from

IE9 Test Drive

The IE 9 Platform Preview doesn’t include the IE 9 user interface; instead, it is the plumbing, specifically the new Microsoft JavaScript engine (which is codenamed “Chakra”) and the new graphics subsystem, coupled with a home page full of test sites. There’s no back button and no built-in security. It’s basically the IE 9 rendering engine and early developer tools.


HTML5 is basically the talk of the town right now, assuming your town is populated exclusively by web developers and Apple apologists. It’s magic! It’s going to save the internet! It’s going to kill Flash! Etc. But really, it’s more subtle than that: It’s the next version of the entire language that underlies the web—HTML—and it supports a lot of interesting features, which will make websites behave more like apps. Firefox, Safari, Chrome and Opera have pretty much left Microsoft in the dust in terms for HTML5 support. Until now! Here are the HTML5 features Microsoft says IE9 will support:

h.264 video: When people talk about HTML5 killing Flash, this is what they’re talking about. Some video sites, like YouTube and Vimeo, have been experimenting with video playback that doesn’t require a plugin to play. h.264 is the format standard the big sites have chosen to go with, and now Internet Explorer will support it.

Embedded Audio: Just as the video tag allows for video to be embedded directly into a page without a plugin, the audio tag allows audio files to be embedded straight into the page. IE9 supports MP3/AAC codecs.

Scalable Vector Graphics: Scalable vector graphics allow for the creation of certain types of graphics that scale perfectly—because they’re drawn as vectors, not plain images. It can also allow for rudimentary, Flash-style animations.

CSS3: CSS is essentially what the web is formatted with, and Internet Explorer’s various CSS compatibilities have been maddening since, well, forever. IE9 supports more standards-based CSS3—including Selectors, Namespaces, Color, Values, Backgrounds and Borders and fonts—and should support more before launch. They’re finally trying, is the point.

Sorry XP user!

According to an article written by Mary-Jo Foley at ZDNet, IE9 will NOT support the Windows XP OS.

Dean Hachamovitch, General Manager of the IE team, said in a Q&A with press and analysts following the keynote that IE 9 will NOT support XP. The preview runs on Vista SP2 and higher.

OS market share

According to W3Schools OS Platform Statistics Windows XP has 50%+ of the OS market share.
