IE 9.0.1 Available via Windows Update

The June 2011 Cumulative Security Update for Internet Explorer is now available via Windows Update. This security update resolves seven vulnerabilities in Internet Explorer that were disclosed in coordination with Microsoft.

The vulnerabilities could allow remote code execution if a user visits a malicious, specially crafted Web page using IE. Users who run without administrative rights are more secure in general and should be less impacted than other users; you can read more about this security principle (link) in many places (link). This security update is rated Critical for IE6, 7, 8, and 9 on Windows clients; for more information about the ratings and the vulnerabilities, please see the full bulletin.

Most customers have enabled automatic updating and do not need to take any action. We recommend that customers who have not enabled automatic updating, enable it (Start Menu, type “Windows Update”). We recommend that administrators, enterprise installations, and end users who want to install this security update manually, apply the update immediately using update management software or by checking for updates using the Microsoft Update service.

Changes to “About Internet Explorer” in IE9

With this update, IE9’s About box shows that the version is now 9.0.1:

IE9’s About dialog after update showing version number 9.0.1
IE9’s About dialog after update (Tools menu [gear icon] > About Internet Explorer)

Every Microsoft update has an associated article (e.g. KB2530548) with technical details about fixes included in the release. These updates are “cumulative,” so the latest update represents all the fixes to date. As we update IE9, we will include a link to that article for the release. We will also update the version number of IE to reflect these changes. The major and minor version numbers remain 9.0; today we increment the update revision to 1. Note that there is no change to the User-Agent string or other platform versioning information.

    I think IE team  should release the next update of IE as IE10 and call the dev build after it gets in beta IE11 or IE13

    @Jace: Any company which says anything against any open source software or technology is a Microsoft minion sent to wreak havoc and impose closed source software/technologies and must be destroyed. Duh.

    Version 9.0.1, nice. Finally version numbers we can understand

  5. Blake says:

    Cool! Neat to see the change log that went in to this update. Didn't know you guys did that.

  6. Jack says:

    Ig this was google's chrome browser, they would give it version 10. Or perhaps even 11   😉

    Just spent the last half hour trying to fix IE on my mom's computer. She keeps getting this message

    "a program on your computer has corrupted your default search provider for internet explorer…."

    Went for the brute force option of resetting internet explorer to default settings, the message still appears though. Searching the internet forums suggest editing the registry, I wonder if the team have a better answer, this problem seems to have been around since at least April. Should I expect my mother to edit her registry or should I just suggest she switches browser.

  8. Michael says:

    @frustrated, Try Manage add-ons –> Search Providers, and choose some other search engine for the default one, also attempt to remove the one that is causing the trouble.

  9. Typhoon87 says:

    @frustrated its probably a browser add on or toolbar trying to change it possibly more than one at a time. Try disabing toolbars and browser helper objects.

    @Michael –

    While there actually was an Internet Explorer 5 for Macintosh, about ten years ago or so.

    However, no new version was released since then, so, right now, there is actually no (otherwise supported) Internet Explorer for Macintosh.

    I wanted Product ID.

    Thank you.

    Greetings we are Anonymous,  with the thought of microsoft not allowing 3d party themes without patching the windows theme files is dumb. so microsoft expect server problems.

    Am I the only one that doesn't get the point of this post? Good for you, an update. Did that really need a special blog post? The only things that are different are that this is the first IE9 update (*meh*)and the version number will be updated (glad to see it). Is that the point? It'd be nice if you could just point that out (as the point of this post) explicitly and cut the rest of the fluff in this post. Heck, that could've been a tweet: "first #ie9 update introduces simpler versioning… introducing #ie 9.0.1"

  14. fr says:

    @Michael It is normal and useful for IEblog to post when an update is released to make people aware of it.  The explanation of the changes for IE9 updates is also useful, it is not a long post and is clear enough.

  15. RobertWrayUK says:

    @Michael, and for those that don't use Twitter?

  16. Sterling says:

    @Michael Flanakin: Have you been to the Chrome Releases Blog? Every update to the browser gets a post on the blog. I like knowing when IE is updated.

    Hey Guys

    Great work with IE9, looks like you getting there, and Bing is making progress, against Google!


  18. Coolmario88cp says:

    Great work with IE9 its very fast.

    "While there actually was an Internet Explorer 5 for Macintosh, about ten years ago or so."

    Yea, it was based on Tasman, which was much more standards-compliant than Trident at that time, making me wonder why wasn't Tasman ported to Windows.

  20. Prior Semblance says:

    You guys might want to make the blog review any comment that is way over the typical length.  Also lol at anybody thinking this light spam could crash a server.

  21. about:blank says:

    Please support IE10 on Windows Vista SP2.

  22. Typhoon87 says:

    I agree with about:blank please reconsider Vista Sp2 support for IE 10

  23. Francis says:

    No one seems to have mentioned this anywhere but IE 9.0.1 actually loads faster than the previous version and tabs also open quicker than before even with the same slow addons present.

    Nice work guys, keep it up.

  24. Vista says:

    Guys come on we all know microsoft might make IE10 for Vista cause i think there should be a Windows Vista SP3 made for Vista.  if not then get ubuntu its better for you

    For the WebGL fanboys:…/webgl-considered-harmful.aspx

    Warning: OT

    Today Microsoft said WebGL is insecure by design. Fair enough, they might be right, but I would like to hear someone from the IE team say that this has nothing to do with OpenGL/DirectX. That is, that the IE team has really considered WebGL seriously, including implementation details (such as how to implement OpenGL in WIndows with different video cards, a la Google project ANGLE).

    The usual Microsoft guard dogs (no offense, really) need not reply that WebGL is unsuitable as a web standard. By the same token HTML, CSS and JavaScript aren't suitable as a web standard.

  27. AntiOpenSource says:

    Lolllll @meni, you are soooooo clueless. WebGL DOES NOT compete with DirectX AT ALL. Implementing WebGL has nothing to do with DirectX/OpenGL. OpenGL will never be supported in Windows — simply because OpenGL is so pathetic compared to DirectX. But WebGL is totally different — it won't be implemented because of security reasons. DirectX FTW. Closed Source FTW.

  28. Aethec says:

    @meni: HTML, CSS and JavaScript do not give you low-level access to the graphics card. WebGL does.

  29. Jace says:


    This isn't even really news.

    WebGL – A New Dimension for Browser Exploitation…/webgl

    Tell me what Contextis has to do with OpenGL vs Directx?

    Hi there.

    Seems you added a bug (or feature?) to the latest 9.0.1 update so HTML5 video sources can not be changed at runtime. tried a video.src = "newSrcURL"; video.load(); but changes to the video element, same video played as before. Hope you can fix it soon!!!
