Microsoft Security Bulletin MS15-032 (3038314)This critical security update resolves vulnerabilities in Internet Explorer. For more information, please see Microsoft Security Bulletin MS15-032.

Security Update for Flash Player (3049508)

This security update for Adobe Flash Player in Internet Explorer 10 and 11 on supported editions of Windows 8, Windows 8.1 and Windows Server 2012 and Windows Server 2012 R2 is also available. The details of the vulnerabilities are documented in Adobe security bulletin APSB15-06. This update addresses the vulnerabilities in Adobe Flash Player by updating the affected Adobe Flash binaries contained within Internet Explorer 10 and Internet Explorer 11. For more information, please see Microsoft Security Advisory 2755801.

Disabling SSL 3.0

As communicated in our February 2015 security updates blog, today we’re releasing an update that disables SSL 3.0 by default in Internet Explorer 11. Enterprise customers can choose to enable SSL 3.0 for compatibility with their web applications, however we strongly recommend instead that they update their web servers and web applications to use latest security protocols such as TLS 1.2. For more information, please see Microsoft Security Advisory 3009008.

Staying up-to-date

Most customers have automatic updates enabled and will not need to take any action because these updates will be downloaded and installed automatically. Customers who have automatic updates disabled need to check for updates and install this update manually.

    What about the IE blocking the entire machine and freezing the mouse bug?  Go to WSJ.com wall street journal and right click open in new tab on each news headline one at a time waiting for each to load.  One or more of them will freeze IE for 10 – 30 seconds.  This happens on other sites all when opening link in a new tab – Windows 7 64 bit machines with the latest OS and IE patches as of March 2015.

    This critical security update resolves vulnerabilities in Internet Explorer."

    I hope it will.  Is there any word yet on when it will be possible to install this critical security update?

    IE 11 をアンインストールして、Windows 7 元の IE8 で検索プロバイダを追加して、IE 11 を再インストールしたら検索設定は継続する経験があります。KB3038314 のインストールにそのまま失敗しましたけど。noname 様は KB3038314 をインストールした方法はどう出来ましたか。

    When I uninstalled IE 11, used Windows 7's original IE 8 to add a search provider, and reinstalled IE 11, the search settings remained in place.  But KB3038314 still failed to install.  How did you get KB3038314 to install?

  13. noname says:

    >>Norman Diamond   さん、色々ありがとうございます。

    ちなみに自分は KB3038314 インストールは成功しました。

    普通Windows Updateでインストール成功です(Win7SP1の32ビット+IE11)。

    noname 様

    Windows 7 SP1 32bit vs. 64bit の異なりは大切かも知れませんね。私は 64bit です。

    Maybe the difference between 32bit and 64bit is important.  I have 64bit.

    それながら、IE11 アンインストール → IE8 で設定 → IE11 の再インストールを実験すれば、設定は残りますか。

    別の2台のコンピュータには IE11 の影響は Outlook 2003 を壊せたから一旦 IE10 に戻ったが最近に IE11 を再インストールしました。

    On 2 other PCs I also had trouble with IE11 so I reverted to IE10, but later reinstalled IE11 again, and settings were preserved.

    For me, IE11's biggest problem was that IE11 broke Outlook 2003.

    So, maybe you can experiment by uninstalling IE11, setting your search provider in IE10, and reinstalling IE11.


    先日私が KB3038314 のインストールに失敗したコンピュータは直接 IE8 から IE11 へ切り替えました。

    別の2台のコンピュータは過去で IE8 → IE9 → IE10 → IE11 → IE10 → IE11 の切り替えをしました。

    当2台には、KB3038314 のインストールは成功しました。

    KB3038314 後に検索プロバイダを変更していません。実験すれば失敗の可能性が高いですね。実験していませんけど。

    Just now, I had another thought.

    A few days ago KB3038314 failed to install on one PC, but that PC had switched directly from IE8 to IE11.

    Previously 2 other computers had switched IE8 → IE9 → IE10 → IE11 → IE10 → IE11.

    On those 2 computers, KB3038314 installed properly.

    After KB3038314 I didn't change search providers.  If I experiment, maybe it will fail.  I haven't experimented though.

    The performance of replacing a large innerHtml element and the replaceChild method are significantly slower across all IE versions now. The size of the innerHtml element content being replaced is 1MB, where previously it took 300ms to execute the call now takes 40 seconds.

    Cut and paste from Ms Word 2010 and 2013 only takes information up to the first carriage return.  IE11

  20. TD says:

    Run this test in IE below with 1000000 on node.innerHtml, it takes 3 s in Chrome, 40 in IE

    It would appear the April Patches have been causing network delays with some web applications; they have been postponed in my environment until further notice.  However, I would like to add the new feature "IE 7 Enterprise Mode" is actually addressing issues for some legacy web apps where IE 8 EM alone wasn't getting the job done.  Being able to trigger 'Compat View' at the site level rather than the domain level is a nice addition to the EMIE suite.  Good Job!
