Microsoft just announced that Internet Explorer 10 for Windows 7 will not be ready by the time that Windows 8 arrives. The software giant announced on its IEBlog that a Preview version of IE10 for Windows 7 will be made available in mid-November, but it remains unknown when the final version will be published.
IE10 on Windows 7 has the same standards based platform for developers to target as IE10 on Windows 8. We built an entirely new browser with Windows 8, with more performance and developer capabilities. IE10 brings improved real-world site performance and additional standards support to Windows 7 that Web developers have been asking for. We look forward to getting your feedback on IE10 on Windows 7, and will provide another update when the preview is available.
