Internet Explorer 11.0.9600.17126 (11.0.9 Update)

Internet Explorer 11 is fast and fluid, allowing websites to perform like native applications on your PC. With the release of Windows 8.1 Preview, Internet Explorer 11 continues Microsoft’s vision of delivering the best web experience across all Windows devices and screen sizes.

On Windows 8.1, Internet Explorer 11 offers the fastest browsing experience, helping you access your sites quickly. It feels fluid and touch-friendly, with features like multiple tabs, richer suggestions, organized favorites, and side-by-side views for comparing websites or using them alongside Windows Store apps.

Internet Explorer 11 empowers developers to create cutting-edge web experiences with professional-grade video, lightning-fast 2D and 3D graphics, and full hardware acceleration. IE11 supports industry-standard technologies and ensures compatibility while offering new developer tools to build high-performance web applications.

Internet Explorer 11 Features:

• Fast: Internet Explorer 11 harnesses the untapped power of your PC, delivering pages full of vivid graphics, smoother video, and interactive content.
• Easy: Experience the web the way you want to with pinned sites, built-in Spellcheck, and seamless integration with your PC running Windows 7.
• Safer: Improved features such as SmartScreen Filter and Tracking Protection help you stay more aware of threats to your PC and personal data.

Faster, More Responsive Browsing

Internet Explorer 11 introduces new features to enhance real-world website performance. It is the first browser to natively decode JPG images in real-time using the GPU, allowing pages to load faster, use less memory, and reduce power consumption, which improves battery life. IE11 is also the first browser to render text on the GPU. Since text and images are central to the web, this accelerated performance benefits nearly every page you view.

Loading web pages faster requires smarter content fetching. IE11 is the first browser to implement the W3C Resource Priorities standard, allowing developers to specify which parts of a page should load first. It also supports HTML5 link prefetching and pre-rendering, helping the browser anticipate where you’ll navigate next and load those pages in advance. On Windows 8.1, IE11 supports the SPDY network protocol, a precursor to the HTTP 2.0 specification, enabling faster downloads for certain websites.

Leading JavaScript Performance

Internet Explorer 11 enhances the performance of our JavaScript engine, Chakra, while maintaining compatibility, interoperability, and security. The JIT compiler now supports additional optimizations, including polymorphic property caching and function call inlining, allowing more code to be JIT-compiled and reducing time spent on JavaScript execution. Garbage collection has been improved to use background threads more efficiently, significantly reducing the frequency and duration of UI thread blocking during garbage collection.

Hardware-Accelerated 3D Web Graphics

Internet Explorer 11 supports WebGL, an emerging web technology that allows developers to create advanced 2D and 3D experiences by leveraging the computer’s Graphics Processing Unit (GPU). Once primarily used for experimental projects, WebGL has become an essential part of web developers’ toolkits, with real-world sites now utilizing it to create interactive visualizations in shopping, real estate, and social networking.

Professional-Quality Video Experiences on the Web

Internet Explorer 11 enables high-quality, power-efficient HTML5 video playback without requiring plugins. It supports the latest standards for closed captioning (TTML and SDP), ensuring that your video content can match professional quality. Additionally, IE11 includes support for the HTML Full Screen API, making it easy to maximize the screen during video playback. With WebCrypto support, websites can directly manage how critical data is encrypted and exchanged. Furthermore, IE can now download video data without caching it to disk, resulting in extended battery life while you enjoy your favorite videos.

All-new F12 Developer Tools Experience Makes Building Sites Easier

Internet Explorer 11 features a completely redesigned and enhanced suite of in-browser F12 developer tools. These tools assist web developers in diagnosing and optimizing their applications quickly and efficiently. Fast and reliable web apps are more critical than ever.

The new F12 supports fast, iterative workflow used by modern Web developers. F12 helps developers get from problem to solution with actionable data, enabling fast and fluid Web experiences. The F12 tools include:

• UI Responsiveness and Memory Profiling tools that help developers diagnose and fix performance issues
• Live DOM Explorer and CSS inspection tools that update with the page so developers can iteratively explore how IE is laying out and rendering Web apps
• JavaScript debugging that starts quickly without a page refresh so developers can get to work more quickly
