Microsoft to start Blocking out-of-date Flash ActiveX controls from October

 

Microsoft has announced it’s expanding the out-of-date ActiveX control blocking feature to include outdated versions of Adobe Flash Player starting on October 11, 2016. This update notifies you when a Web page tries to load a Flash ActiveX control older than (but not including):

  • Adobe Flash Player version 21.0.0.198
  • Adobe Flash Player Extended Support Release version 18.0.0.241

You can view the complete list of out-of-date ActiveX controls being blocked by this feature here.

If you are running Windows Server 2012R2, Windows 8.1, and Windows 10, you will not by impacted by this change. By default, Windows Update will automatically install important Flash updates as they become available for Internet Explorer and Microsoft Edge on those systems.

Supported configurations and scope of out-of-date Flash ActiveX control blocking

Unlike out-of-date Java and Silverlight blocking, the following caveats are additionally applicable to out-of-date Flash ActiveX control blocking.

Supported configurations

Out-of-date Flash ActiveX control blocking only applies to Internet Explorer 11 on Windows 7 SP1 or Windows Server 2008 R2.

For enterprise users, out-of-date ActiveX controls aren’t blocked in the Local Intranet Zone or the Trusted Sites Zone, so intranet sites and trusted line-of-business apps should continue to use ActiveX controls without any disruption.

Scope

First, with out-of-date Flash ActiveX control blocking, Internet Explorer will only warn you once per tab process. All subsequent out-of-date Flash ActiveX controls will be allowed.

Second, users who are not members of the Local Administrators group on the PC will not see any out-of-date Flash ActiveX control blocks.

The term of out-of-date Flash ActiveX control blocking will end on November 10, 2016.
