Updates to out-of-date ActiveX control blocking coming in November
As we shared back in September, and as part of our ongoing commitment to delivering a more secure browser, we want to help you stay up-to-date with the latest versions of popularly installed ActiveX controls. Today, we’d like to share two exciting updates to the out-of-date ActiveX control blocking feature: updates to our supported operating system and browser combinations and out-of-date Silverlight blocking.
Out-of-date ActiveX control blocking on Windows Vista SP2 and Windows Server 2008 SP2
Beginning January 12, 2016, we’re going to support the following operating system and browser combinations (for more info, see this announcement):
|Windows operating system||Internet Explorer version|
|Windows Vista SP2||Internet Explorer 9|
|Windows Server 2008 SP2||Internet Explorer 9|
|Windows 7 SP1||Internet Explorer 11|
|Windows Server 2008 R2 SP1||Internet Explorer 11|
|Windows 8.1||Internet Explorer 11|
|Windows Server 2012||Internet Explorer 10|
|Windows Server 2012 R2||Internet Explorer 11|
Right now, the out-of-date ActiveX control blocking feature works on all of these combinations except Windows Vista SP2 and Windows Server 2008 SP2 with Internet Explorer 9. Support for these combinations is expected to start on November 11, 2014.
Out-of-date Silverlight blocking
Starting on November 11, 2014, we’re expanding the out-of-date ActiveX control blocking feature to block outdated versions of Silverlight. This update notifies you when a Web page tries to load a Silverlight ActiveX control older than (but not including) Silverlight 5.1.30514.0.
You can continue to view the complete list of out-of-date ActiveX controls being blocked by this feature here.
Enterprise testing for out-of-date Silverlight ActiveX control blocking
Remember, out-of-date ActiveX controls aren’t blocked in the Local Intranet Zone or the Trusted Sites Zone, so your intranet sites and trusted line-of-business apps should continue to use ActiveX controls without any disruption.
If you want to see what happens when an employee goes to a Web page with an out-of-date Silverlight ActiveX control after November 11, 2014, you can run this test.
- On a test computer, install the most recent cumulative update for Internet Explorer.
- Open a command prompt and run this command to stop downloading updated versions of the versionlist.xml file:
reg add "HKCU\Software\Microsoft\Internet Explorer\VersionManager" /v DownloadVersionList /t REG_DWORD /d 0 /f
Important: After you’re done testing, delete this registry key. If you don’t, this computer will stop receiving the updated VersionList.xml file with all of the out-of-date ActiveX controls. Because of this, we don’t recommend setting this registry key in your production environment.
Important: After you’re done testing, replace this file with its production version from here. We don’t recommend manually changing the versionlist.xml file in your production environment.
You’ll now get an out-of-date ActiveX control blocking notice when a Web site tries to load an outdated Silverlight ActiveX control.
If you need more time to minimize your reliance on outdated Silverlight controls, see the Out-of-date ActiveX control blocking on managed devices section of the Out-of-date ActiveX control blocking topic.
