Internet Explorer Automatic Component Activation (IE ACA) Update is an optional preview for IE that will disable the Click to activate behavior of the embedded ActiveX controls on web page implemented by KB912812 update that was originally released in April 2006. After adding the warning notice, users require to approve and activate ActiveX controls, such as embedded Flash video or media, Windows Media Player applet, and PDF document display before running the component for the first time.
According to IEBlog, the change will require no modifications to existing web pages, and no new actions for developers creating new pages. IE 6 and 7 browsers are simply reverting to the old behavior. Once Internet Explorer is updated, all pages that currently require “Click to activate” will no longer require the control to be activated. They’ll just work. The update is made possible after Microsoft licensed the technology from Eolas in a out-of-court settlement after losing the copyright infringement suit on the security measure. The out-of-count settlement no longer needs Microsoft to provide separate “Click to activate” control to supplement IE.
The IE ACA Update is available for a number of IB build versions that has the “click to activate” function enabled, including IE6 and IE7 for 32-bit (x86) and 64-bit (x64) of Windows XP, Windows Server 2003, and Windows Vista. All releases can be downloaded for free from KB945007.
Note that users must apply and install Internet Explorer security update MS07-069 (KB942615) before deploying IE ACA update, to ensure that computers are up to date with functionality that is required and contains latest security fixes. MS07-069 or Knowledge Base article 942615 has been distributed through Automatic Update. If you don’t have Automatic Update enabled, run Windows Update or Microsoft Update and check for updates to install it. This step also possible avoid chance to has the “click to activate” behavior reverted back when installing MS07-069 IE security update as the package is cumulative and contain all previously released updates for each version of Internet Explorer, including update that applies the “click to activate” on IE controls.
The IE ACA update preview will not be distributed widely via Windows Update yet. The final release of this IE refresh to remove the “Click to activate” feature is scheduled on April 2008, and will be released as part of an IE Cumulative Update.
