Blocked out-of-date ActiveX controls

[!INCLUDE Microsoft 365 workloads end of support for IE11]

ActiveX controls are small apps that let websites 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 Unfortunately, because many ActiveX controls aren't automatically updated, they can become outdated as new versions are released.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that you keep your ActiveX controls up to date because malicious software (or malware) can target security flaws in outdated controls, damaging your computer by collecting info from it, installing unwanted software, or by letting someone else control it remotely. To help avoid this situation, Internet Explorer includes a security feature called out-of-date ActiveX control blocking.

We'll periodically update this page with new ActiveX controls blocked by this feature. We'll typically provide one month's advance notice before adding new controls to the list.

You will receive a notification if a webpage tries to load one of the following of ActiveX control versions:

Java

Java 2 Platform, Standard Edition (J2SE) 1.4, everything below (but not including) update 43
J2SE 5.0, everything below (but not including) update 99
Java SE 6, everything below (but not including) update 181
Java SE 7, everything below (but not including) update 171
Java SE 8, everything below (but not including) update 161
Java SE 9, everything below (but not including) update 4

Silverlight

Everything below (but not including) Silverlight 5.1.50907.0
