As we
announced last month, Project Spartan will be the new browser across all Windows 10 devices, from phones to tablets, PCs and beyond. You’ll hear about the new browser’s features in the coming months but in this post, we want to tell you more about what motivated us to build a new rendering engine focused on interoperability with other modern browsers ― all in the name of making the Web “just work” for our customers. This new rendering engine was designed with Project Spartan in mind, but will also be available in Internet Explorer on Windows 10 for enterprises and other customers who require legacy extensibility support.
Modernizing IE while not breaking the Web
Internet Explorer has been the Microsoft Web browser for 20 years and has evolved to work with ever-changing Web sites over that time. Since 2009, we’ve been systematically bringing major investments to the browser to modernize each of
the browser subsystems: from fast new JavaScript and layout engines, GPU-accelerated rendering and 3D graphics, and multi-threaded touch input to improved F12 developer tools and backwards compatibility with Enterprise Mode.
