IE10 for Windows 7 Globally Available for Consumers and Businesses

Internet Explorer 10 is available worldwide in 95 languages for download today. We will begin auto updating Windows 7 customers to IE10 in the weeks ahead, starting today with customers running the IE10 Release Preview. With this final release, IE10 brings the same leading standards support, with improved performance, security, privacy, reliability that consumers enjoy on Windows 8, to Windows 7 customers.

20% faster for real world Web sites

With IE10 we continue delivering the best performance for real world Web sites on your Windows device. As with Windows 8, IE10 on Windows 7 improves performance across the board with faster page loading, faster interactivity, and faster JavaScript performance, while reducing CPU usage and improving battery life on mobile PCs. In measurements in our performance lab, IE loads real world pages up to 20% faster in top sites for news, social, search, ecommerce, and more.

You can experience IE10’s leading performance first hand with demos on the IE Test Drive site with examples of hardware accelerated rendering, interactivity, touch, and real world site patterns. Minesweeper is a new test drive demo that is both a full featured HTML5 game and also lets you measure your browser’s performance.

Enjoy a full featured HTML5 Minesweeper experience and test your browser’s performance

Minesweeper is built on a breadth of Web platform capabilities including HTML5, CSS3, WOFF, touch, animations, transitions, audio, video, canvas, transforms, and power efficiency patterns. The game uses standards-based mark-up for interoperability across browsers, and makes the most of fully hardware accelerated browsers like IE10 on both Windows 7 and Windows 8, with consistent performance across a wide range of devices including tablets like the Surface RT. Minesweeper’s performance mode measures how long it takes the browser to solve the minesweeper board, so you can test your browser performance with different minesweeper boards with different complexity.

IE10 also improves hardware accelerated performance of SVG and HTML4 constructs. You can see improvements yourself with the Chalkboard test drive where performance improves over IE9 by 15%. Similarly, improved drawing performance enables faster rendering patterns you can experience yourself with the Speed Reading test drive where performance improves by 30% over IE9 on comparable hardware.

IE10 continues to lead on JavaScript performance with many improvements to the Chakra JavaScript engine including profile-based, type-specialized JIT machine code, faster floating point operations, faster object and property access, and more. All of these improvements come to IE10 on Windows 7 and are consistent across the underlying operating system and hardware. As a result, with IE10 on Windows 7, performance on the WebKit SunSpider JavaScript benchmark improves by 25% over IE9 and leads the industry and other browsers by 17%.

In addition to raw performance improvements of real world sites, IE10 includes improvements to make common browsing activities you do every day faster. IE10’s integrated spell checking and auto-correct for common spelling mistakes, makes typing text for blog posts, social updates, and tweets faster and less error prone. Similarly, we tuned the tabs bar so closing many tabs is faster and more efficient, without having to moving your mouse as each tab closes.

60% increase in supported modern Web standards

For developers, IE10 brings increased support for modern Web standards powered by hardware acceleration to enable a new class of compelling applications and fast and fluid Web browsing. IE10 adds support for over 30 new modern Web standards beyond IE9, for a 60% increase. These new supported standards in IE10 include many of the latest HTML5, CSS3, DOM, Web Performance, and Web Application specifications across important aspects of Web development including:

  • Create rich visual effects with CSS Text Shadow, CSS 3D Transforms, CSS3 Transitions and Animations, CSS3 Gradient, and SVG Filter Effects
  • More sophisticated and responsive page layouts with CSS3 for publication quality page layouts and responsive application UI (CSS3 grid, flexbox, multi-column, positioned floats, regions, and hyphenation), HTML5 Forms, input controls, and validation
  • Enhanced Web programming model for better offline applications through local storage with IndexedDB and the HTML5 Application Cache; Web Sockets, HTML5 History, Async scripts, HTML5 File APIs, HTML5 Drag-drop, HTML5 Sandboxing, Web workers, ES5 Strict mode support.
  • Beautiful and interactive Web applications with support for several new technologies like CSS3 Positioned Floats, HTML5 Drag-drop, File Reader API, Media Query Listeners, Pointer Events, and HTML5 Forms.
  • Improved Web application security with the same markup and support for HTML5 Sandbox for iframe isolation.

You can read more at the IE Developer Center and the updated IE10 Guide for Developers about the full set of new Web standards supported in IE10. Listed below with links to the W3C specifications.

AppCache HTML Editing APIs
Clipboard APIs and events HTML5 async attribute
Content Security Policy HTML5 Parser
Cross Origin Resource Sharing (CORS) HTML5 Sandbox attribute

Furthering our commitment to privacy

In keeping with our commitment on prioritizing the privacy of our customers, the Do Not Track (DNT) signal is turned on in IE10 for Windows 7. In addition to Tracking Protection, IE continues to lead in providing increased choice and control over your privacy online. Customers can choose to turn-off the DNT signal in the options settings in Internet Explorer.

Our commitment to keeping Windows customers in control of their privacy and data sharing continues, especially in the current environment of so much user data being collected online without explicit consent or user awareness.

A better Web today and ahead

The opportunities continue for HTML5 to make both Web sites and applications better. Those opportunities are exciting for everyone on the Web. Like IE10 on Windows 8, this release brings high performance HTML5 development to Windows 7.

For developers building on HTML5, now is time to get ready for IE 10. Developers can use the recently launched modern.IE to test and verify your sites, using a wizard that scans a Web page URL for common interoperability problems and suggests some ideas for how to address those issues to improve the user experience across modern and older browsers.

On behalf of the individuals and companies who have worked with us to deliver this product, and the many people at Microsoft who have built it, thank you for your feedback and for using IE10.

— Rob Mauceri, Group Program Manager, Internet Explorer

    ~ M 4 Microsoft, Metallica & Nothing Else Matters!

  2. It's 2013 says:

    Yeah, it's not like we've been asking you to do this for the better part of a decade or anything…

  3. jsdev says:

    What about WebGL?

  4. Yay! FINALLY!!!! …took you guys long enough! …now, let's hope that Microsoft commit to regular updates to their browser, and not let it "stagnate" again between releases!

  5. IE user says:

    IE 10 is good.

  6. MgSm88 says:

    I hope for the next version you guys focus on making the developer tools better. They are much clunkier and harder to use than Chrome's. I absolutely hate trying to debug something in IE. Features needed:

    – Source map support

    – Better way to explore objects in the JS console. (See how Chrome has collapsible nodes and can handle nested objects.)

    – Better way to log objects. (See how Chrome's console.log() behaves, it allows you to explore the object, printing "[object Object]" is entirely useless.)

    – Better JS console user interface (I hate the behavior of it, why is there a single line and multi line mode? It should just *work*. I don't want to think about how I'm supposed to use it. Horrible UX design.)

    – Thinner header (3 lines of stuff before you get to the content of the debug tools?)

    – Ability to break on DOM modification of specific elements (ala Chrome).

    – "Refresh page to see messages that may have occurred"/Start capturing network traffic. Why does this all need to be explicit? I should just turn on "developer mode" in some setting somewhere and it should capture/log all this by default.

    – Ability to see applied vs defined styles and how styles are overriding each other.

    I also wish you guys would move to a more frequent release schedule with more incremental updates. If every other tech company can be agile with their browser releases, why can't MS? Just have milestones with long-term support, like Firefox has adopted, and you can make corporate customers happy while not hampering innovation.

  7. Eamon Nerbonne says:

    Is there a list of bugfixes anywhere, particularly those since the release preview?

    Has the aero portrait issue been fixed, in which a portrait mode monitor disabled aero after installation of one of the IE10 prereq updates?

  8. Eamon Nerbonne says:

    (addendum to a previous question concerning a bug that causes aero to fail once IE10 is installed):

    Link to a description of the problem:…/fe813f9b-023b-4fe1-a677-a97ec359960f

  9. dd26 says:

    I'd heard that your rationale for not implementing WebGL was security.  In what way does WebGL compromise it?  Chrome & FF have it and I've yet to hear of any incidents related to it.  Please reconsider adding WebGL.

  10. Given that IE10 for Windows 7 uses ClearType, any chance IE10 (or even IE11) for Windows 8 could be made to do the same?

  11. N says:

    Sure would be nice to see a response to @MgSm88 and @dd26

  12. Chaz6 says:

    Please support WebGL.

  13. Steve says:

    Does this mean that a fix for the IE Blog comment form is just around the corner?

  14. @ AT

    So migrate away from MS products & technologies then!

  15. Islander says:

    I found a bug with CSS3 text-shadow / color property. When changing color opacity of the text (doesn't matter if using transparent as color or by rgba alpha value), said opacity also effects the shadow. For example, if I want to make the text half transparent in order to show more of the shadow… the shadow also appears half transparent. IE10 is the only text-shadow supporting browser with that flaw, any other browser has no problems with it.

  16. Entegy says:

    I think someone has anger issues…

  17. dd26 says:

    @Get IE – yes -that doc re: WebGL.  Why not have an opt-in?  If you really think these are vulnerabilities why not give the user the option to take on that risk if it indeed exists?  You could include the reasons in a disclaimer and warn the user beforehand, similar to setting the lowest security settings, i.e. "not advisable" or for expert users only.  When it comes to networking, nothing under the sun, alas, is fully secure.

  18. petmal says:

    The IE10 scroll bar does not fit into the Windows 7 UI. Please, make the default look & feel consistent with the target OS. You certainly won't get any more users for Windows 8 this way…

  19. Here's an interesting "quirk" (quite literally!) …if you go into F12 Developer Tools, the "Document Modes" available (apart from "Standards" are "Quirks") are:

    Internet Explorer 9 standards

    Internet Explorer 8 standards

    Internet Explorer 7 standards

    Internet Explorer 5 quirks


  20. FD says:

    Javascript JIT compiler is implemented on IE10 x64? Because IE9 only implemented it on 32bit version…


  21. Ificator says:

    @Eamon Nerbonne: The answer appears to be "no it's not fixed" since I've now lost aero functionality on my work machine…

  22. alvatrus says:

    Thanks for the (belated) release.

    Can you guys now start talking a bit more about the IE11 features?

  23. Yannick says:

    @GreatMarko – Don't worry, it's not IE5. It's just the Quirks mode of IE10, why Internet Explorer 5 is mentioned, I've no clue.

  24. Meni says:

    Please stop mentioning WebGL here, ok? Like, WebGL, OpenGL, DirectX, get it? Hell will frieze before some suit at Microsoft will sign on that. Waste of energy. After all what does Microsoft has left? XAML and DirectX. Just a few more years until these die.

  25. Arieta says:

    @Yannick: Actually, it IS the IE5 rendering mode. It's there so you can check how sites without valid doctypes would look in IE5-9. It's a legacy thing, and while it's far from 100% accurate, it helps fixing major bugs.

  26. chrisweb says:

    Thank you microsoft. As a web developer i really appreciate the move.

    Like most commenters i dont like microsoft, i dont like you because i think your browser update strategy is not adapted to the modern web and therefore blocking the emergence of new web technologies. But this one is a nice move i had to honor with a comment ๐Ÿ˜‰

  27. Yuhong Bao says:

    @Yannick: I think this is based on the IE7 rendering engine's quirks mode, which is supposed to emulate IE 5.5.

  28. Stuart says:

    Have updated to IE10.  It seems to work fine.  I like the fresher-looking appearance and the newer web-page controls.

  29. Over a year ago, when you started showing IE10, I was excited.  But now, you are way behind, AGAIN.  Why did it take so long to deliver this?  Waiting for this release is literally holding back the internet as too many people are still using older versions of IE.  If Microsoft truly wanted to advance the web, this would have been released months ago.  I used to be a Microsoft fan, but you guys are making it too hard.

  30. Arieta says:

    Turns out the memory leak is still present in this final version, a huge regression since IE9. Oh well.

  31. firefox1993 says:

    Internet Explorer still sucks as it don't have WebM support.. webM is a important part of html5 and I don't believe we should have to download a plugin/addon/file to get webm in internet exploder.   Come on Microsoft release another update for IE10 that will add webm support to IE  it needs it.. look at chrome and firefox they all have fully video support for webm and h.264

  32. kwerboom says:

    After all my complaining, I just want to say, "Thank you".

  33. Bill says:

    Are there any plans for an IE10 VPC disk image? It doesn't look like the download page has been updated.…/details.aspx

  34. Arieta says:


    IE supported WebM since IE9, as an optional codec.

  35. Mark says:

    A colleague updated to IE 10 and the web browser is not working at all. No Internet connectivity whatsoever, and his system is not restoring to the point it worked. Solutions? This is majorly impacting his ability to get work done.

    E-mail works so there is not an issue with connectivity.

  36. Yannick says:

    Firefox1993 – It's An important part of HTML5, except that It's NOT part of HTML5.

  37. Imran Khalid says:

    I just want to say, Thank you Microsoft ๐Ÿ™‚

  38. @RobCannon says:

    I actually can't think of much that has changed in any browser in the past few months, why is IE10 far behind now if it wasn't back then?

    Anyway, does anyone know if Microsoft has posted a list of changes made from the preview version?

  39. Arieta says:

    Well, the bug where IE10 can't display RSS feeds if "show active content in my computer" is enabled, seems to be fixed.

  40. Firefox1993 says:

    @Yannick it is check out the video part of  it has it listed so it is part of the <video> element.  Face it internet explorer will die  soon…  I'm never switching back to IE..  IE = Internet Exploder..   I know a lot as I made my own linux distro from scratch its not public yet though.

  41. @Firefox1993 says:

    Believe it or not, random websites don't get to choose what is and isn't html5.

  42. @Firefox1993 says:

    haha you are so clueless and funny. thanks for making my day

  43. Nick says:

    "Why not give the user the option…?" Because the check box is the mating call of the loser.…/9416485.aspx

  44. Sceptic says:

    If you don't provide a webgl implementation, at least don't put out an incompatible "standard" of yours like the CSS shaders crap you tried to pull(Why do you let your devs ridicule themselves on public lists?). You have every right to be obsolete but no right to bring the web's evolution to a standstill, AGAIN. Thank you

  45. Ian says:

    I hope Windows 7 gets IE11!! It deserves it!

  46. jonathantneal says:

    I noticed that the option to "Install new versions automatically" is enabled by default on first run in IE10. Thank you so much!

    Will this be limited to security updates, or will this include feature updates as well?

  47. Joel says:

    They should consider renaming the browser to lessen the stigma, or keep legacy versions as IE and rebrand a new, improved version.

  48. Ashley says:

    Has anyone else been through that Minesweeper demo source code? There's some weird stuff in there. See…/De… – in solve():

        //run some webkit sunspider code before solving a square


    In solvenextsquare():

       // run some webkit sunspider code a few times before continuing


        //not done solving, run more webkit sunspider, we hear that's what users want

    It looks like the "benchmark" is to run bits of sunspider while running a minesweeper game. I think this is somewhat misleading. If you want to highlight the fact that IE10 is good at sunspider, then say so, but I think the current way you've presented it makes it look like a benchmark for HTML5 gaming when it is not.

  49. reg says:

    I am not up on all these new things. All I want is to be able to use IE like I have in IE8. I like the drop down menu, I like the way it looks. Can anyone tell me this:

    Is IE going to be automatically put onto your computer? If so, will it override IE8? Can it be put on as a separate browser and still keep IE8?

    I have tried Firefox and Chrome and dislike both immensely.

    Any responses would be greatly appreciated.

  50. Anon says:

    The image on IE 10's download page is still labeled by its alt attribute as "Internet Explorer 10 Preview".

  52. IE10 Windows 7 Fails says:

    Wow what a bunch of FAILS Microsoft – ouch!

    1) the windows metro ugly and usability challenges scrollbars are NOT welcome in Windows 7 for **ANY** app!

    2) the drop down rendering with the 2px solid flat border is again not only ugly but not at all in line with windows 7 themes – major regression in style and natural discoverability.

    3) why did the download attempt to install Bingware and MSNware on **my** PC?!?! Would I not already have that garbage installed if I actually wanted that bloatware?!?!

    4) HTML 5 scores are still the lowest of all browsers

    5) iframe rendering is delayed causing sticky boxes when scrolling

    6) I ABSOLUTELY DID NOT ALLOW you to make MSN my home page!!!!

    7) CTRL + A in the home page TextArea (eg to delete the setting you had no permission to set! Does not enable a select all!!!

    8) OMFG!!! Are you serious!!! I just set it to blank, saved it, closed IE and on restart it has reset MSN as my homepage! IE is now officially a virus!

    I'm not adding any more to this list… Going straight to the antivirus software makers to file IE as a virus!

  53. Anon says:

    As I was installing IE 10 I closed the setup window and it went away without showing any dialog or asking for a cancellation of the setup process etc. Now I can't get IE 10 to install again. If I run the setup again, it says that "an IE installation is currently in progress". What should I do?

  54. @Islander

    Thanks for your report! IE is following the W3C spec correctly by using the used value of the color property (including the alpha value) for the default color for text-shadow.

    CSS Text Level 4 says, "<shadow> is the same as defined for the 'box-shadow' property except that the 'inset' keyword is not allowed." The box-shadow property is defined in CSS Backgrounds and Borders Level 3. For the box-shadow property, that specification says, "If the color is absent, the used color is taken from the 'color' property."

    You can define an explicit color in your text-shadow value if you want it to use a different color.

  55. Anon says:

    The setup program is sloppily written. First it says "downloading updates" even though this is the RTM version of IE 10 and it takes a long time to do it too.

    Then, it has no cancel button and if you dare to close the setup window the setup process keeps lingering in the background leaving the installation in a half done state. It is hard to get out of this mess afterwards.

    Then, when you first open IE 10 and go to Help > What's new in IE 10, you get a horrible page that tells you "Thank you for running IE 10 preview. Please click here to update". But I am already running IE 10, what are you talking about?

    You click "here to update" and it says:

    "The setup program cannot finish"

    What do you mean by finish? It hasn't started yet you wonder.

    "You are running a later version of IE so setup cannot continue."

    What do you mean, you wonder again?

    Sloppy sloppy sloppy sloppy sloppy.

  56. Anon2 says:

    Just installed IE10 in W7.  It works great – and it's super-fast.  Nice work guys.  Can't wait to start building sites for this awesome app.

  57. Firefox1993 says:

    At Least Firefox has a great community while  the internet explorer community has been dieing down since 2004.. IE is under 10% of browser market  Firefox has won the sooner you all accept it the better it will be..  IE uses activeX  the most virus attacked thing out there..

  59. Susan says:

    Dear anon – it really is downloading updates  –…/en-us it installs that stuff in the background.  The installer IS installing updates.

  60. Anon says:

    I also tried out spell checking, one of the new features of IE 10 and found it badly designed.

    1. It does not work in all text boxes but only where the developer has set a special attribute. In other words, on the great majority of websites, forget it. It does not work.

    2. Right-clicking a misspelled word allows you to add the misspelling to "the dictionary". However, there is no indication on how to remove a word once added to that so called "dictionary". Once in there, it's always there. Wherever that dictionary with all the my exceptions might be stored. Who knows. I looked under Tools > Addons > Spelling Correction and no, the exceptions dictionary is not there.

    3. Right-clicking an auto-corrected word allows you to stop auto-correcting it. But again, there is no way to restart auto-correcting it, if you make a mistake in the first place.

    4. Right-clicking a mispelling shows a rich Language submenu with the ability to choose the active language, etc. Not when right-clicking a previously auto-corrected word. Only "Stop correcting …" appears without the Language submenu. Why this inconsistency? To say nothing of the fact that a Language submenu would have been useful regardless if the word was misspelled or not, i.e. it should always be there even if you right-click a correct word.

    5. Why provide the ability to choose the active language using the Language submenu? I thought Windows 7+ could now auto-detect the language of a piece of text. Isn't that so?

  61. Anon says:

    6. The Language submenu is badly designed. Only one language is shown and there is a deeper More submenu with the rest of the languages. Why not put every language in the Language submenu. What is the purpose of More, if the main Language submenu shows only the active language?

    7. Going to the spell checker's settings under Tools > Addons > Spelling Correction, you find a checkbox that reads "Enable Spelling Correction". What does it do? Enable/disable spell checking? Enable/disable auto-correction? Most likely the former but still not very cnclear. And if it is the former, how do I turn off only auto-correction?

    8. In the same settings dialog, you find a button that reads "Get more spelling dictionaries online …". But regardless the number of times you click it, nothing happens. No website opens. It is broken.

    9. Again in the same settings dialog, there is a combo box which allows you to choose if you want to see the "Installed languages" or "All dictionaries". I have no idea what this combo box filter does! First, what's the difference between a "language" and a "dictionary"? Why didn't you call the two choices "Installed dictionaries" vs. "All dictionaries", instead of using the word "languages" for the first and "dictionaries" for the second choice? Secondly and most importantly, if there is a "Get more spelling dictionaries online …" button, what is the need for the "All dictionaries" filter? I get the feeling that this filter displays all the available language dictionaries by fetching them from an online service and allows you to install any one you choose. Correct? Well, I tried selecting it and it does not work. It shows an empty list.

    10. I tried…/Default.html. Why is the site in IE 10 Compatibility view? Checked using the Developer tools. Why not in IE 10 Standards Mode?

    Chrome does not have all these usability issues that I discovered in 5 minutes of usage and it can auto-detect the language used as well.

  62. CSS Column Bug in IE 10. says:

    CSS Column Bug in IE 10.

    There is a bug in newly added Column support in IE10.

    Following page renders differently on IE 10 from all other browsers – FF,Chrome,Safari

    (the text is suppose to wrap around the image)

    Please fix this bug, but any work around in the meanwhile?

    Thank you so much.


  63. Bug in this site, can not click to image for slideshow while still OK in firefox or chrome or IE9.…/loi-khuyen-huu-ich-tu-nhung-nguoi-thanh-cong.htm

  64. @anon says:

    Re point 1 it does work on any html text-area (normally a multi line box) by default, but not on input type=text (single line box) because this type of field is regularly used for inputting details that the spell checker would think was misspelt when it wasn't eg email addresses.  It makes sense therefore to allow the developer of the page to set which fields of that type should have spell check.  It works the same way in Firefox by default, not sure about the other browsers.

  65. @ CSS Column Bug in IE 10. says:

    It might help if you included all resources into your file! If you reference "queryly.util.imageLoad" you should have it defined somewhere.

  66. some idiot says:

    But why can't it save passwords, nor use saved passwords? I tried it for 120 minutes yesterday, but eventually had to revert back to IE9. Please fix this annoying bug.

  67. Anon says:


    "Dear anon – it really is downloading updates."

    Thanks Susan, I did not know.

    But why didn't they say "Downloading prerequisits" instead of "updates"? It would have been understandable whilst now it makes no sense. This is what Visual Studio Setup says and I never had any problem understanding it.

    Good design and attention to details is what makes excellent software that shines, as opposed to software that is just fine.

  68. @brijeshbihani says:

    IE10 in W7,works great – and it's super-fast.  Nice work guys

  69. Middle mouse button bug for ie10 rtm says:


    ie10 rtm for win7๏ผŒ10.0.9200.16521


    1 This bug only for "power users" account . "administrators" and "users" no this bug.

    2 A new account  whith in "power users" groups,middle mouse button click a link,always open in new window,right is new tab.

    3 Change this account  groups  from "power users"  to "administrators".Log in again .Middle mouse button click a link , ok.

  70. michel says:

    How about fixing the long-standing password bug?

  71. Anon says:

    Also, I went to a page and I got a 405 error. Nevermind the exact error code; it might have been 404 instead. The problem is that when I click the "More information" button to get more details on the error, I basically get a repetition of the same infromation I got above and it asks me to look at help for more information. Then, when I go to Help, I get a generic website that has no content whatsoever concerning error codes, even after you search for the word error on it.

    So, there is a "Mor information" button that actually should be called "Repeat same useless information", which asks you to go to IE's help without linking you to it and we have a help system that is basically a generic MS website without any mention of any error codes.

    What do you make of that? Excellent design? Or "just average"?

  72. jabberwolf says:

    OK I love IE 10 speedwise and page compatibility wise it seems better than chrome or firefox (yeah I don't care what the metrics say on some browsers, I think something is wrong with them.

    BUT… IE 10  seems to have BROKEN Aero or anything with translucency. I cant even get to personalization, windows colors, (it jumps right into advanced and no access to change colors). That I no longer have page preview of the pages down on my taskbar. MS seriously needs to add a reinstall of fix page for these functions.- For now I am uninstalling it. I REALLY wanted to like IE10 … but MS is pissing me off with this bad testing.

  73. Stephen says:

    When I installed IE10 on Windows 7 is set my default search provider to Bing.  I specifically UNCHECKED that option on install I'm therefore NOT IMPRESSED!

    I will never in a million years want Bing to do anything on my computer ever.  There's a good reason why Google has a 97% market share in search – because it works, and because it is NOT Bing, Not Microsoft.

    I've fixed the setting (well, set Google back to be the default, then removed Bing).  I expect that Microsoft will respect my preference and NEVER set Bing automatically for ANYTHING ever again.

    First impressions of IE10? Less than spectacular.

    Everytime Microsoft writes same-markup interoperability, a baby kitten d-i-e-s an horrible d.e.a.t.h. Go fix your browser bugs before making my life as a web developer harder than already is having to support 5 broken browsers.

  76. IE-man says:

    There's no difference in IE9 and IE10 other than the scrollbar.

  77. Aleksandar says:

    Does anyone at Microsoft read comments from your own blog?

  78. Akber Ali says:

    Couple of weeks back I downloaded IE10 on my Win 7 64 Bit, ultimate machine and soon I found that It needs to do a lot. Even the compatibility mode won't show certain sites properly. I mean i am the person who always use bing, windows, windows phone, but I had to uninstall it. Trust me after its installation my outlook 2010 stopped working properly.

  79. SS says:

    Sounds to me like our organization will use the tool that blocks installation of IE10 for our domain.  I haven't used IE10 yet, but if even if half the comments here are remotely accurate, we don't want it in its current incarnation.

  80. S Thomas says:

    Great news. Thanks.

  81. Anon says:

    Why is Gmail being displayed in Compatibility View? The page has the correct doctype and it even say  "edge" in the meta tags.

  82. Jiggaboo says:

    I downloaded IE10 then went to IETestDrive.…/AudioExplosion – and it tells me that I don't have browser that supports MSGesture APIs, Pointer Events (which you describe here IE10 does support) HTML5Canvas, HTML5Audio. It tells me to update to latest version of IE to see what web has been waiting for! Ok so I go there and click Update Internet Explorer and it tells me …  that I can't do it because I have a more recent version. WTF!? Are you kidding me? I wasted like 3 hours installing and uninstalling it thinking I am doing sth wrong!

  83. Firefox says:

    Firefox Aurora now full HTML5 <video> Support download now at

  84. @Anon says:

    I've been using IE10 for months and have less complaints than you have in a day…

  85. Memory Issue says:

    Can anybody confirm this: Open task manager (Click on CTRL + Alt + Del)..Enter this site and see how memory amount increases:

  86. @Memory issue says:


  87. @ Memory Issue says:

    Depends on your graphics system (probably driver quality).

    On my Laptop (Mobile Intel(R) 965 Express Chipset Family) the memory amount increases indefinitely (I stopped the test at 1.000.000 kb), but IE10 remained responsive.

    On my Desktop PC (NVidia GTX 660) the memory increases up to 420.000kb and maxes out there. Just for comparison the GIF you have linked to uses 360.000kb in Irfan View. With the additional overhead in the browser pretty much what you would expect.

  88. Junk says:

    Why I can't close tab by middle button – clicking on the tab?

    IE 10.0.9200.16521

  89. Dbauer says:

    Two problems that I encountered with IE10:

    (1) Providing exceptions to the popup blocker does not work.  Every popup is blocked.

    (2) Readjusting the toolbars is not saved.  The next time you launch IE10, the toolbars revert to their default positions.

    Until these are fixed, I am continuing to use Chrome.

  90. pmbAustin says:

    Funny thing.  I go to the "Mine-sweeper" test on my Win8 laptop at home, and yeah, it runs a lot faster than under Chrome.  But at the place where Chrome puts up the time at the end… the IE10 browser simply crashes.  Repeatedly.  Every time.  

    Obviously this doesn't happen for everyone… but, it'd sure be nice if MS's own "bragging site" didn't crash horrifically on their own browser on my system.

  91. siljaline says:

    Most will see the below link as the default download link:…/download-ie (this gets you the thanks for looking at the preview now go get the RTM)  I'm seeing a number of places where the false thanks-preview link comes up, this is most annoying.

    Also, do IE 9 TPL's work on IE 10 RTM ? Someone forgot to mention this as TPL's are (among many reasons) why most are choosing to upgrade to IE 10.

    Improved support pages would also be appreciated as I'm not seeing any as of this writing.

    Could someone also get with the program at and fix the TPL listings there ?

    Other than the above beefs, it works and is welcome – some ads-ons to improve  the rather "flat" UI would be welcome.


  92. yahsukram says:

    IE is to web browsers what Etch A Sketch is to art.

  93. Evan says:

    If the IE blog can't set cookies correctly and can't make a blog comment form that works properly how are we supposed to take the blog owner/maintainer *Microsoft* even remotely seriously when it comes to browser development and following standards?

    You talk a lot of talk yet you're still the worst performing browser in HTML5 tests!

    I just fail to see how we can take your statements as anything but fodder when you still ship a browser that supports security hole magnets like Active-X?!

    Please tell us that in IE11 Active-X will no longer be supported in any mode (quirks, metro, or standards)!

  94. Mayur Prayag ( India ) says:

    Current IE Team is not brilliant ,talented.They can't think from user's view.Steven ,Please Remove IE development team ,appoint new team like Windows 7 team or give project to Google ,they will develop IE like Chrome and later you tell world that we(Microsoft) developed "the IE"…..but finally we will get better IE ….Please reply me or guaranty me that future IE will be a benchmark …..the best…..better than Chrome……

    Below are IE's failure Reasons:

    1) IE's UI feels very heavy when first opened.

    2) IE is not simple means back button and forward button is not light.

    3) IE is slow

    4) IE takes more time when loading Facebook and Twitter…..!!!!!!

    5) Give IE's development to  "Google" and they will tell you how to develop a web browser.

    6) Please,copy the chrome UI ,responsiveness , simpleness…..then and then only IE will be great         otherwise whatever mini Internet,millions test you do ,it is of no use……

    7) chrome feels very light and IE feels like ton of load on our head..

    8) when we open any site IE ask for default browser in a very sluggish manner…

    9)  IE smart screen filter very slow takes much time

    10) Remove status bar from IE

    11) Take some development lessons from Google Team so that you can develop OS like Android and browser like Chrome….

    12) Within 3 years Google showed your position in market(Browser)…

    13) Microsoft is not very serious about IE…

    14) Current IE 9 is like Windows Vista ,make some strict steps and give IE 10 like Windows 7,8 performance …..

    15) Make proper Acid 3 tests,because when user sees Acid 3 tests after release on various sites,they give very less marks to Internet Explorer….

    16) Make UI clean,again I'm giving warning otherwise within 5 years you will lost completely..

    17) When we Right Click on empty space,a lot of items appear…..Remove many items(Translation etc) from right click

    18) Keep less items for Right click …..we want that

    19)Current IE Team is not brilliant ,talented.

    20)They can't think from user's view

                                                             Most Importantly, All will agree that,        "  Last thing ,we all people wanted that IE must beat chrome…….when we double click chrome icon on desktop ,it opens smoothly and feel softs,smoother …..whereas IE feels like scratches on our Screen,skin etc……!!!!!!!!!!!!!!!!.."

    I hope you will take a lesson from above .I'm an end user.

    This final version is causing a problem with FlashPlayer where flash apps freeze when mouse is moving.

    It didn't happen with Release Preview.

  96. AMX says:

    The flattened, Windows 8-like interface looks out of place on Windows 7…

    IE9 was simply "prettier" than IE10 ๐Ÿ™

  97. Envio says:

    Glad it's finally here but like AMX said, the UI elements from Windows 8 including borders, scroll bars, drop-down menus simply do not fit and jar against Windows 7's UI.  I assume this was a deliberate decision but I can't think why, it just looks bad, sloppy.

  98. DT says:

    IE10 doesn't pass Acid 2 (see the eyes) or even Acid 1 (see the text "i grow old"), despite passing Acid 3. What's up with that???

  99. @DT says:

    acid2 is based on old versions of W3C standards that have been superseded by newer versions of web standards.

    That alone could have an effect on the test.

    For instance IE10 could have dropped support for a feature that has been deprecated in CSS2.x after the introduction of CSS 3.x

  100. DT says:

    I see how that could be. Firefox passes all three Acid tests though…

  101. @DT says:

    My IE 10 passes the 3 tests.

  102. Will says:

    Absolutely hate the cheesy tablet UI on IE in Windows 7!

    Looks hideous on windows 8 too but at least it is consistent there.

  103. Auto says:

    Why IE10 has the fewer points of all others browsers in the HTML5 test web site?

    Even 58 points less than Safari.…/desktop.html

    I think this should be improved a bit.

  104. DT says:

    I have tested IE10 on Win7 with and without add-ons, and IE10 on Win8 under Metro and Desktop on a brand-new Surface Pro tablet (fully updated through Windows Update) and neither Acid1 or Acid2 match the reference rendering.

  105. John S says:

    HTML5 scores still well behind Chrome already! Really Microsoft, can you try and push stuff out a little faster? I also totally agree that the scroll bar looks awful in Windows 7. Really Microsoft, do you have to add a little Windows 8 into everything now?

  106. Mr. says:

    They are not gonna change it back. ๐Ÿ™‚

  107. Robert S says:

    Ironic! IE10 for Windows 7 now includes a spell-checker, but the Brazilian Portuguese version is full of translations/spelling errors.. ๐Ÿ™ and the spelling options haven't even been translated… really disappointing Microsoft… giving up!

  108. Mayur Prayag ( India ) says:

    @ Yannick

    1) According to u , everthing is good enough about IE 10.Then Can u please tell me So-Called " HTML 5 " score of IE 10

       in comparison with others.

    2) Why r there lack of all Add-ons in IE since it's inception. Other browsers have literally all add-ons,extensions ….(Like              ADBlock,crickinfo ,Glamsham..etc)

    3)  Why r we using 1995 dialog box of Internet Options ,why not METRO style new dialog (setting) Box so that all options r discoverable.

    4) IE 10 much more time while deleting History .Period.

    5) Address Bar is at Top left side instead of middle of screen.It takes pain while moving mouse from right to left.

    6) Why should not we get automatic .extensions while typing (Like .com,.org.,net) thus could reduce user's pain.

    7) There is not a Copy- And- Paste ,Copy- And -Go Option like chrome.I think Microsoft tries to give more pain to end users which is not their habit.( It's habit of UNIX Users…)

    8) Most important thing when u save a web page i.e. "Save Page As" it doesn't save page properly.Also it takes minutes

      to save page .

    9) It doesn't save page in background like Chrome so that we have to wait ideal while it saves it…Really bad for a

       company like Microsoft.

    10) while opening new Tab ,it takes more time .Take a lesson from Opera,Firefox.

    11) Build a Download Manager of IE like IDM plus in-built Torrent Support so that we don't need IDM .we must able to download videos from IE's

       Download Manager itself.( It would be great idea…..what u think guys)

    12) Finally ,at last Print preview is like 20 years old box.It must be like chrome in-built in same window.

    13) Improve UI upto some extent

    14) Develop new version within a gap of 1 that major OS includes best of the Best IE.

                                     If above points r done correctly, I don't think No one can come near close to IE.Guys I want reply from all of u .Microsoft team reply me….If this done, It would be my dream IE ever.Period….. Awaiting reply

  109. Mayur Prayag ( India ) says:

    Again there isn't Exclusive Internet Explorer Store like windows ,windows phone.

    Launch IE store so that All add-ons can be developed for IE.( Wishlist ADBlock  first……)

    reply me………….

  110. Martijn Saly says:

    Finally IE10 is out on a proper desktop OS. Sorry, I do not consider Windows 8 a desktop OS, because the frigging start panel is missing. But now we can have IE10 all around.

    Microsoft, be a good boy and do the same for IE11 please. That also needs to be on Windows 7 (and it can, but you have to be willing not to disallow it).

  111. Martijn Saly says:

    @Mayur Prayag

    Forget about that, IE is not extensible. Period.

    You want extensibility? Opera (a little), Chrome (a bit more) and Firefox (all the way, baby).

  112. PhistucK says:

    @Martijn Saly, Mayur Prayag –

    Internet Explorer is very much extensible, just not using JavaScript/HTML/CSS, but using native code. It has been so ever since Internet Explorer 4 – or maybe even earlier.

    I am not sure how extensible it is and what exactly can be changed, but I do know for a fact that it is extensible.

  113. @Martijn saly says:

    The start panel is not realy missing from W8 but has changed to a full screen start panel.

    You can just as easily add things to the W8 startscreen as you could do to the W7 start menu.

    It just looks and feels different.

  114. IE User says:

    IE10 sometimes crashes when starting it. And then it restarts. I have Google as start page.

  117. Like Aero says:

    Can't we have the option of keeping the Aero look for IE10?  I'm just an end user, and I really like Aero.  It's the reason I'm not even thinking about upgrading to Win 8.  

  118. Scott says:

    I love how many folks here are calling bugs in web pages as if they are bugs in I.E.  Get a clue folks.

    Also, so much confusion over what is HTML5 and what is not.

    And, the "broken page" icon (appropriately named) still works for all those outdated web sites, of which IE10 makes many more outdated as they should be.

  119. I'm looking forward to installing IE10 on my Win7 Asus F3F :).

    Bravo to microsoft….

  125. John says:

    How does IE10 help me overcome the many third party applications that are critical to my business that still required IE6, IE7,.. and how does IE10 offer me a future that breaks this enormous side by side issues. Enterprise like the ones I represent are not being melitious in their approach to upgrades, there are many strong business reasons we cannot move of older versions of IE based application at the speed that Microsoft would like the rest of the world do move at.

    I like the constant improvements Microsoft makes, but unfortunately dealing with Microsoft software is not like dealing with IBM or like buing a car.  If Microsoft was a car manufacturer then when a new car was introduced all of us drivers would have to learn new road rules and take our drivers license test again and all the older models car and drivers would have to either operate on their own roads, with many change stations, or have to get off the roads all together.

    I'm sure if Microsoft tackled this problem in the same way it did security, then we would get a viable answer, and it would stop us looking at alternatives whenever a new product is realised or the version we are running comes to the end of life.

    Please help us

  129. I can't see the damn scroll bar. Who the hell thought grey on white, with a 2D button, was in any way even viable FFS?

    For that matter, the entire browser is now 2D. Will we just turn the PC off and use paper and pencil for the next version?

    Please fix this major flaw.

  130. Kris Mac says:

    In my first hour of use, it crashed twice and when viewing sites in ie 9/8/7 mode, reported javascript errors that actual ie7/8/9 dont throw.

    Im having to uninstall it for the mean time as I need to be able to reliably test ie9 and dont have a VM for it yet, hopefully some patches will be released soon

  131. JBurton says:

    I downloaded and installed IE10, using this web site and it left me with  and internet browser that was non-functional.  It froze up every time I started it up.  This happened on 2 PC's.  Microsoft won't get many customers if this sort of thing keeps happening.  I'm not a novice either.

  132. Praveen says:

    I really liked IE10. After 2 years, I will be using IE.

    Yes IE10 is a good browser.
