Internet Explorer and the Windows 10 Technical Preview


Today, the Windows 10 Technical Preview was launched to give an early look at what’s next for Windows. Only available to install by joining the Windows Insider Program, the Technical Preview is also the best way to see the latest from Internet Explorer so join today. In this post we’re sharing what’s new for IE as well as launching the Internet Explorer Platform Suggestion Box for web developers to give us feature suggestions using the UserVoice platform.

What’s new for IE on the Windows 10 Technical Preview

HTTP/2

Internet Explorer on the Windows 10 Technical Preview includes support for new the HTTP/2 networking protocol which is a standardized effort with broad industry support. HTTP/2 builds on our experience delivering SPDY/3 support in IE11 and enables improved performance on the Web using techniques including multiplexing, header compression and Server Push.

Performance improvements to the Chakra JavaScript engine

IE on the Windows 10 Technical Preview also includes several performance improvements in our Chakra JavaScript engine. The changes include streamlining of Chakra’s execution pipeline to deliver faster startup, optimizations in Chakra’s Just-in-Time compiler to increase script execution throughput, and enhancements to Chakra’s Garbage Collection subsystem to deliver better UI responsiveness for apps and sites.

Interoperable Top Level Domain Parsing

IE on the Windows 10 Technical Preview switches the parsing of domain names to use the algorithms and domain list found at http://publicsuffix.org.

Launching the IE Platform Suggestion Box on UserVoice

We’re also announcing today the availability of the IE Platform Suggestion Box, based on the UserVoice feedback platform. This is the latest step in the effort that we announced last April to build a better two-way conversation with web developers, including our monthly #AskIE sessions and our fun Reddit AmA in August.

By using the UserVoice voting system, we’ll be able to see exactly which feature suggestions are the most requested by the web developer community which will help us prioritize our work. We also linked the vote counts directly into status.modern.ie to make it even easier to get us your feedback on new standards and features.

Note that specific bug reports should continue to be reported via Connect. For feedback on the Internet Explorer user experience, please use the Windows Feedback app built into the Windows 10 Technical Preview.

Test driving the latest IE web platform

In addition to improved feedback channels, we are also committed to helping web developers get their hands on the latest IE web platform. In June, we launched the IE Developer Channel which was available to be installed side-by-side with the released version of IE11. Through the great feedback we received, many of the features previewed in the IE Developer Channel were shipped in the August update for IE11.

To continue previewing the latest IE web platform, join the Windows Insider Program and install the Windows 10 Technical Preview. Once you join the Windows Insider Program, you’ll be subscribed to regular preview build updates and keeps you on the leading edge of Windows and Internet Explorer.

Lots more to come

We’re just scratching the surface and look forward to sharing more details in coming blog posts on HTTP/2, Chakra performance improvements, top-level domain parsing changes and the Internet Explorer Platform Suggestion Box. To learn more, be sure to join us on October 2nd at 10AM-12PM PST for our regular #AskIE Twitter chat hosted by @IEDevChat.

  1. Great work, guys! Is HTTP2 unblocked for use everywhere? E.g. WinINET-based callers? URLMon callers? WebOC hosts other than Internet Explorer itself?

  2. Dan says:

    Where is  metro IE in windows 10?

  3. Saurabh_kr says:

    Thanx…

  4. Yannick says:

    Great and all, but… where is the Modern UI version of Internet Explorer in Windows 10? Anyway, I hope to see a lot more coming. 🙂

  5. CvP says:

    Please fix SPDY ignoring TPL. Since you are saying HTTP/2 is build on your experience with SPDY, fix HTTP/2 ignoring TPL too if that is the case.

  6. wiki says:

    Could you post a URL where we can try out HTTP/2? Thanks!

  7. Daniel says:

    So … I guess not much is new, huh?

  8. noname aaa says:

    What happened to IE12?

    Does it come out also for turning Windows 7 again?

    As soon as it is decided, please let me know by a blog.

  9. Aeyoun says:

    Whatever happen to /browserconfig.xml, Live Tiles, and stuff like that? “Enhanced pinned tabs”. I see there is a new “Add website to apps” option, but that is no better than the IE9-stuff.

  10. Charles Morris [MSFT] says:

    @Dan/Yannick: As you saw in other Windows 10 announcements yesterday and today, universal apps and the unification of the mouse/keyboard and touch environments are big themes for Windows 10. We're working to move the IE experience in a consistent direction. The removal of the second browser is just the first of many steps on that path. Stay tuned!

  11. Charles Morris [MSFT] says:

    @Aeyoun – this is just the beginning. Let us know what you'd like to see for pinned sites at http://uservoice.modern.ie.

  12. Nic says:

    Hi,

    What about a preview for Windows 7 users?

    Thank you

    Thank you

  14. _bug_ says:

    Looking forward to it!

  15. wiki says:

    OK, I have found a website that supports HTTP/2: webtide.com/http2-draft-14-is-live Also in the Protocol column, could you call it "HTTP/2" rather than "HTTP2"? In tools.ietf.org/…/draft-ietf-httpbis-http2-14, HTTP/2 is far more frequently used than HTTP2.

  16. SHOAIB IQBAL says:

    Tnxs 🙂

  17. nikonian says:

    I will be installing it this weekend. Is the Metro version of Skype deprecated as well? To save us all time, could you please list the Metro-ized apps that have been removed? Thanks.

  18. @nikonian says:

    And who said *anything* about depricated apps? You can just install on you Windows 8/8.1 system using Hype-V and see for yourself: Store is working!

    Dear developer IE12, answer finally have such a burning question: Will the IE12 available for previous OS Windows, namely 7 and 8.1?

  20. David Walp [MSFT} says:

    @wiki: Draft 14 Implementers have their sites listed under github.com/…/Implementations

  21. gg says:

    thanks for keeping us up-to-date and letting us use 'user voice' which is better suited to discussing out thoughts! 🙂

  22. SG says:

    Cool. Very Cool. Keep up the good fight.

  23. Charles Morris [MSFT] says:

    @Nic We're looking at ways to bring latest IE preview to Windows 7. Stay tuned! In the meantime, getting the Technical Preview is the way to go.

  24. anon says:

    For those wondering about Modern IE on the Windows 10 Technical Preview, check the Programs tab of Internet Options.

  25. Internet Exploder says:

    Why do people still ask about Win7? It's pretty obvious by the time IE12 ships, Win7 already entered extended support which excludes any new features being developed for it and only gets security updates until 2020.

    End of mainstream support

    End of extended support

  26. Thanks for the preview bits. Maybe I missed it, but has anything been announced about the new IIS, eg HTTP/2 support?

  27. David Walp [MSFT] says:

    @ EricLaw:  WinINet interface supports HTTP/2 but requires opting-in.  HTTP/2 is on by default for IE.  HTTP/2 is on by default for WWA & Webview. Other Webplatforms off by default. WebOC off by default, opt in via FCK.

  28. David Walp [MSFT] says:

    @Christiaan Rakowski: IIS support HTTP/2 but is currently limited to secure connections only.

  29. Farrukh Momin says:

    I do use IE as my primary browser although i have chrome, Firefox and safari in my laptop but they are waiting for their turn. There seems a problem I noticed is when IE as a really long page to render it stuck badly. Same thing happens top Facebook and all the site that has endless page. It lags severely.

    by the way believe it or not IE is the lightest and fasted among all the browsers I have installed in my laptop.

  30. Blade says:

    so… this is Win 8.1, with a new IE?

  31. Blade says:

    nevermind, I didn't realize I had clicked into the IE blog.. i'm a derper.

  32. Maxim-064044 says:

    @Charles Morris [MSFT]: thanks you for the hope! But then you have a legitimate question: when will the release of the next version of Developer Channel, or the project is losing relevance?

  33. Dan says:

    Support of HTTP/2 means both encrypted and clear text formats are supported, right?

  34. _bug_ says:

    In fact I do wonder when IE12 will come…

  35. ven says:

    How can i back up IE Bookmarks ?

  36. Brian says:

    @ven: The way I do it is open file manager, open c: directory, open users, click on your name, right click on favorites then select copy and then paste it to whatever media you want to use.

  37. pmbAustin says:

    IE bookmarks are backed up to the cloud (OneDrive) if you have syncing turned on and log in with a Microsoft ID in Windows 8

  38. jescott418 says:

    So far I find the page loading much improved! I don't miss the Modern IE app. myself but wonder as some have why its not in Win 10?

    I personally never found it that useful other then on my Wife's Surface. Which brings me to a question. Is Microsoft going too much backwards on the tablet UI support in Win 10? I myself mostly use PC's and that's mostly with a mouse and keyboard. But in some ways in the back of my mind like with the loss of Modern IE. If maybe the tablet users will find Win 10 a step back?
