Some users may get unusual messages after applying September Patch Tuesday updates where out-of-date Active X controls are present.  For example, new controls to block outdated JAVA and FLASH extensions may require users to update these components to completely resolve these warning messages. While transition may be a little painful, this serves to better protect users long term from dangerous exploits in outdated IE plug-ins.

QUOTE: As part of our ongoing commitment to delivering a more secure browser, starting September 9th Internet Explorer will block out-of-date ActiveX controls. Note: The original post stated that the ActiveX blocking would begin on August 12th.

ActiveX controls are small apps that let Web sites provide content, like videos and games, and let you interact with content like toolbars. Unfortunately, because many ActiveX controls aren’t automatically updated, they can become outdated as new versions are released. It’s very important that you keep your ActiveX controls up-to-date because malicious or compromised Web pages can target security flaws in outdated controls to collect information, install dangerous software, or by let someone else control your computer remotely.

For example, according to the latest Microsoft Security Intelligence Report, Java exploits represented 84.6% to 98.5% of exploit kit-related detections each month in 2013. These vulnerabilities may have been fixed in recent versions, but users may not know to upgrade. To help avoid this situation with ActiveX controls, an update to Internet Explorer on September 9, 2014 will introduce a new security feature, called out-of-date ActiveX control blocking.

The out-of-date ActiveX control blocking feature works with:

* On Windows 7 SP1, Internet Explorer 8 through Internet Explorer 11
* On Windows 8 and up, Internet Explorer for the desktop
* All Security Zones—such as the Internet Zone—but not the Local Intranet Zone and the Trusted Sites Zone

This feature does not warn about or block ActiveX controls in the Local Intranet Zone or Trusted Sites Zone.
