As expected, Microsoft has just released the Internet Explorer 10 preview for Windows 7. There is still no word on when the final version of the browser will be available, but developers can use the preview to start building optimized sites using IE10's perfomance enhancements and can do so using the same standards based platform that is utilized with the Windows 8 version. Microsoft originally stated that the preview was set to launch mid-November, and the company hit its target right on the nose. Head over to Microsoft's download page to grab the latest version of Internet Explorer right now.
