    • 19 Comments
    Internet Explorer 10 introduces significant improvements in memory protections to help make vulnerabilities harder to exploit, helping to keep users safe on the sometimes-hostile Web. These improvements will increase the difficulty and development cost of exploits, making life harder for the bad guys.

    Google Bypassing User Privacy Settings

    • 156 Comments
    When the IE team heard that Google had bypassed user privacy settings on Safari, we asked ourselves a simple question: is Google circumventing the privacy preferences of Internet Explorer users too? We’ve discovered the answer is yes: Google is employing similar methods to get around the default privacy protections in IE and track IE users with cookies. Below we spell out in more detail what we’ve discovered, as well as recommendations to IE users on how to protect their privacy from...

    Sub-pixel Rendering and the CSS Object Model

    • 9 Comments
    With Windows 8, you have an unprecedented choice of devices for browsing the Web, from large desktop screens to small slates. In order to accommodate this range of devices, the browser must be able to scale and layout the Web at many different screen sizes and dimensions. We've previously blogged about some of the features in IE that support these scenarios. Sub-pixel positioning (of text and layout) is one of the core platform technologies which enable Web pages to look beautiful and consistent...

    CORS for XHR in IE10

    • 9 Comments
    The fourth platform of IE10 simplifies building cross-site scenarios that work consistently across browsers by supporting Cross-Origin Resource Sharing (CORS) for XMLHttpRequest (XHR) .

    High performance HTML5 content in Metro-style Apps

    • 27 Comments
    Metro style apps in Windows 8 have all the performance benefits of IE10 when showing Web content. In Metro style apps, Web content is always JIT compiled and hardware-accelerated. Other platforms do not provide the same level of performance in apps. For example, Cocoa apps on iOS offer significantly worse JavaScript performance (via the UIWebView control) than the same content running in Safari. These Cocoa apps do not enjoy JIT compilation, and these apps cannot show and use Web content the same...

Internet Explorer 10 tile shown not pressed (left) and pressed (right) Adding a...

    Web Sites and a Plug-in Free Web

    • 81 Comments
    The transition to a plug-in free Web is happening today. Any site that uses plug-ins needs to understand what their customers experience when browsing plug-in free. Lots of Web browsing today happens on devices that simply don’t support plug-ins. Even browsers that do support plug-ins offer many ways to run plug-in free. Metro style IE runs plug-in free to improve battery life as well as security, reliability, and privacy for consumers. Previously, we wrote about how we use IE’s Compatibility...
