This video shows some of the performance and developer tools enhancements in IE11 Release Preview for Windows 7
With IE11 on Windows 7, customers receive a fast, secure browser that is compatible with existing Web sites and delivers exciting new interactive Web experiences. For developers, IE11 supports the latest Web standards and technologies, making it easier to build sites that work across devices. The new F12 tools in IE11 enable developers to build high performance Web experiences, faster and more efficiently.
A Faster Web Experience
Performance matters to everyone who browses the Web. The IE11 Release Preview for Windows 7 includes additional performance tuning so that real-world sites download and display fast and are highly responsive and interactive.
Even More Web Standards and Increased Compatibility with Existing Web Sites
IE11 Release Preview for Windows 7 includes updates to reflect the latest emerging Web standards. For example, now that the Pointer Events specification is a Candidate Recommendation at the W3C, IE11 supports an un-prefixed version of the emerging standard. With Pointer Events support across the full range of Windows devices (and soon to other browsers), Web sites can easily build experiences that work equally well with mouse, keyboard, pen, and touch.
IE11 Release Preview for Windows 7 adds new user controls for the Standard Delivery Profile for Closed Captioning. With the new control, accessible from the Internet Options menu, users can customize how captions appear in the browser, even overriding the default styling provided by the video source. This customization further advances IE11 as the best browser for professional-quality online video without plugins.

The IE11 Release Preview for Windows 7 also supports the latest Tracking Preference Expression (DNT) draft in the W3C. After installation, the IE11 Release Preview prompts the user set a default tracking preference that Internet Explorer will send to Web sites. On upgrade, IE11 Release Preview automatically preserves the user’s previous tracking preferences. .
Faster, More Efficient Developer Tools Productivity, Based on Your Feedback
IE11 includes a completely re-designed and enhanced suite of in-browser F12 developer tools. These tools help Web developers diagnose and optimize their apps quickly and efficiently. Having fast and reliable Web apps is more critical than ever.
The IE11 Release Preview for Windows 7 includes several tools enhancements to increase developer productivity and in response to the overwhelming enthusiasm and feedback we have received from developers. Here are just a few of the many improvements:
- Debugger: An improved file picker allows faster access to files in a complex Web project.
- DOM Explorer: With IE11, developers can tune Web sites more quickly by editing CSS property values and seeing those edits in the Live DOM without having to press the enter key
- Memory: To make it easier to narrow down the source of memory leaks, the F12 tool now identifies what operations were performed on allocated data between memory snapshots.
The IE11 Memory tool identifies which memory was allocated, de-allocated, or modified between snapshots, supporting faster memory tuning and diagnosis
- Networking: A new “always refresh from server” option creates reproduceable performance results while developers rapidly iterate to tune their site performance. The tool also includes new Search Next and Search Previous functions for analyzing complex network traces.
With IE11, the “always refresh from server” option supports iterative development by producing reproducible network performance results each time you reload the page
