    IE7 beta 1 – A few details…

    • 392 Comments
    We’ve heard some great feedback on what web developers would like to see in IE7, both from the responses to my last post and from the resources I referred to.  The rest of the team was cranking away while I was away on parental leave, and I wanted to share a few details about what they were doing: The first couple of things they’ve done are: Support the alpha channel in PNG images. We’ve actually had this on our radar for a long time, and have had it supported in the code for a while now. We...

    File URIs in Windows

    • 44 Comments
    Invalid file URIs are among the most common illegal URIs that we were forced to accommodate in IE7. As I mentioned in a previous blog post there is much confusion over how to handle file URIs. The standard for the file scheme doesn’t give specific instructions on how to convert a file system path for a specific operating system into a file URI. While the standard defines the syntax of the file scheme, it leaves the conversion from file system path to file URI up to the implementers. In this...

    IE and Standards

    • 580 Comments
    First of all, I’d like to introduce myself. My name is Chris Wilson; I’m the lead program manager for the web platform in IE. (I am NOT Chris Wilson the drummer for Good Charlotte. :^) ) I joined the IE team shortly before we shipped IE 2.0 in 1995, and worked in various releases for every major release from then until IE 6.0’s release in 2001. After IE 6.0 shipped, I worked on the Avalon project until I decided to rejoin the IE team four months ago. During my tenure on the IE team, I’ve frequently...

    IE7 to be distributed via Automatic Updates!

    • 332 Comments
    As we get close to the final availability of Internet Explorer 7, I want to provide an update on our distribution plans. To help our customers become more secure and up-to-date, we will distribute IE7 as a high-priority update via Automatic Updates (AU) shortly after the final version is released for Windows XP, planned for the fourth quarter of this year. During the past year, we’ve discussed many of the advanced security features in IE7 that will help make our users more secure, including ActiveX...

    Better Website Identification and Extended Validation Certificates in IE7 and Other Browsers

    • 185 Comments
    Today I want to tell you about both our established plan to highlight secure sites in IE7 but also to tell you about some early thinking in the industry about creating stronger standards for identity on the internet. IE7 will join other browsers like Firefox, Opera and Konqueror in making the experience for secure (HTTPS) sites more visible by moving the lock icon into the address bar. We think the address bar is also important for users to see in pop-up windows. A missing address bar creates...

    Microsoft's Interoperability Principles and IE8

    • 650 Comments
    We’ve decided that IE8 will, by default, interpret web content in the most standards compliant way it can. This decision is a change from what we’ve posted previously. Why Change? Microsoft recently published a set of Interoperability Principles . Thinking about IE8’s behavior with these principles in mind, interpreting web content in the most standards compliant way possible is a better thing to do. We think that acting in accordance with principles is important, and IE8’s default is a...

    ClearType Text in IE7

    • 198 Comments
    Hello there, I’m Peter Gurevich, one of the many program managers on the IE team. My primary feature area focus is on the rendering and display in the browser, including the decoding and display of images and the rendering of Text. I wanted to briefly chat with you all about a change to the way IE7 renders text. You may have noticed that after installing IE 7, your fonts in IE and Outlook Express look different. That is because IE7 has changed our text rendering to use ClearType. I...

    Internet Explorer 7 Update

    • 162 Comments
    Almost a year ago, we released Internet Explorer 7 for Windows XP. Since then, IE7 is well on its way to becoming the most used browser in the world, and we’ve seen lots of evidence that IE7 makes it safer and easier to accomplish everyday tasks online. For example, the built-in Phishing Filter has protected consumers from known phishing web sites an average of 900,000 times per week. IE7 is the first – and still the only – browser with native support for Extended Validation SSL Certificates that...

    IE7 Transparent PNG Implementation

    • 148 Comments
    My name is Sam Fortiner and I’m a developer on the Internet Explorer team here at Microsoft. I joined the company about a year ago when I was given the opportunity to work on IE. Since then I’ve worked on several aspects of IE and recently settled down into the layout and display team. As part of my work in this team, I implemented support for per-pixel alpha in PNGs. Support for per-pixel alpha in PNGs in IE, or transparent PNGs as I’ll refer to them going forward, has been called many things...

    HTML5 Video

    • 233 Comments
    There’s been a lot of posting about video and video formats on the web recently. This is a good opportunity to talk about Microsoft’s point of view. The future of the web is HTML5. Microsoft is deeply engaged in the HTML5 process with the W3C . HTML5 will be very important in advancing rich, interactive web applications and site design. The HTML5 specification describes video support without specifying a particular video format. We think H.264 is an excellent format. In its HTML5 support...

    Introducing IE=EmulateIE7

    • 82 Comments
    Bill Gates’ recent Tech Ed keynote and Tony Chor’s follow-up blog announced that IE8 Beta 2 will be available in August in many languages. We are encouraging sites to get ready for Beta 2 prior to release as it will present a big jump in IE8 browsing traffic. What does “getting ready for IE8” mean for web sites? IE8 displays content in IE8 Standards mode – its most standards-compliant layout mode – by default. In previous blog posts, we’ve discussed how this aligns with our commitment to Web standards...

    Internet Explorer 7 User Agent String

    • 155 Comments
    Internet Explorer 7 Beta 1 is fast approaching. A tiny but significant code change was checked in this week: Internet Explorer's new User-Agent string. The User-Agent (or UA) string is sent along in the headers of every HTTP request so the server knows what type of browser is making the request. For a quick introduction on handling of the User-Agent string, check out George Shephard's article in MSDN Magazine. Internet Explorer 7 User-Agent As we updated the User-Agent, we considered application...

    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...

    Windows 2000 moves into Extended Support after June 30th

    • 221 Comments
    There are two important events that will happen to the support policy for Windows 2000 after June 30th of this year. First, support for both IE 5.01 SP3 and IE 6 SP1 on Windows 2000 SP3 will expire. Users running IE 5.01 or IE 6 SP1 on Windows 2000 should upgrade to Windows 2000 SP4 in order to continue to receive security updates. Second, Windows 2000 SP4 moves from mainstream to extended support. The key difference between mainstream support and extended support which I think is most relevant...

    Give Your Eyes a Treat

    • 69 Comments
    If you’re a developer, there’s an easy way to give your eyes a rest and make yourself more productive. Use the Consolas font Microsoft developed specifically for you. When we began work on a project to create a new set of fonts which would take maximum advantage of ClearType, we decided to develop a fixed-pitch font for developers - because no one ever thought of their needs, and we realized a highly-readable fixed-width font would make their lives a lot easier. We call them the C* fonts because...

    IE8 and Privacy

    • 165 Comments
    As others have written here before, users should be in control of their information. That’s at the core of privacy. Privacy has two aspects: disclosure and choice. Disclosure means informing users in plain language about the data collected about them and how it’s used. Choice means putting users in control of their data and giving them tools to protect it. Have you ever wanted to take your web browsing “off the record”? Perhaps you’re using someone else’s computer and you don’t want them to know...

    What Happened to Operation Aborted?

    • 77 Comments
    Have you ever seen this dialog while surfing the web in Internet Explorer? You browse to your favorite news site. The content starts loading, you've already started reading the headline, and then it happens. Those of you familiar with the operation aborted dialog know that it spells sudden doom for the website you're currently viewing. Unsuspecting users have no idea what it means and simply click 'OK' and then watch in horror as the web page they were just reading disappears; only to be replaced...

    Hi! I’m Jane Kim, program manager for RSS in Internet Explorer. Now that Beta 1 of IE 7 for Windows XP and Windows Vista are released, I want to introduce to you the RSS features that are available in this release. You may be asking what RSS is.

    • 105 Comments
    As part of our ongoing commitment to delivering a more secure browser, starting September 9th Internet Explorer will block out-of-date ActiveX controls. Note: The original post stated that the ActiveX blocking would begin on August 12th. Please refer to the addendum for further details. ActiveX controls are small apps that let Web sites provide content, like videos and games, and let you interact with content like toolbars. Unfortunately, because many ActiveX controls aren’t automatically...

This time, I’d like to tell you about the changes IE7 has made to improve the security and user experience for HTTPS connections. Safer Protocol Defaults HTTPS uses encryption to secure your Internet traffic to protect it from snooping or tampering by others on the network.
