Microsoft will release a preview of IE10 on Windows 7 in mid-November, with final availability to follow as the company collects developer and customer feedback. IE10 on Windows 7 has the same standards based platform for developers to target as IE10 on Windows 8. Microsoft said it 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," Microsoft said in a blog post.
