Internet Explorer 10 is available in this developer preview build, as the About dialog box shown here makes clear.
The Trident rendering engine at the core of IE 10 plays a crucial role in Windows 8. You can use Internet Explorer in a Windows desktop session, where (at least for now) it uses the same tabs and interface conventions as IE 9. But if you tap or click the big blue Internet Explorer button on the Start screen, you get the Metro-style browser instead. Swipe the top or bottom edge to display the controls shown here.
