Microsoft has released a platform preview 3 for its Internet Explorer 10, which will be the core browser for Windows 8. The build is available through the developer preview of Windows 8 and offers users two interface options. It features the new Metro UI experience but also supports the traditional Windows desktop interface.
Although it offer both interfaces, it's clear that Microsoft finds the new Metro UI to offer a superior experience. In a blog post, Microsoft Internet Explorer chief Dean Hachamovitch wrote: “While building the entirely new Metro style experience, a funny thing happened: we realized it might just be a better way to browse even if you have a big screen, a desktop computer, and a mouse and keyboard."
Thus, IE10 will run two separate experiences on the same engine, which Microsoft believes is the best route so that no compromises are made. There are also several improvements to performance, safety, and support for HTML 5.
The platform preview 3 for IE10 is only available through the Windows 8 preview for now with future platform previews of IE10 to be made available every 8 to 12 weeks. The final version will only be supported by Windows 7 and Windows 8.
