To have a trustworthy browsing experience, it's important that you are in control of the apps running in your browser. With ActiveX Filtering, you can now browse the Web with more control of your ActiveX controls. You can easily turn on the controls on sites that contain ActiveX content you want to view. This feature successfully limits the content allowed to run ActiveX controls, thus minimizing any potential performance, reliability, security or privacy impact on your browsing experience.
ActiveX Filtering in the IE9 RC gives you greater control over how Web pages run on your PC. With ActiveX Filtering, you can turn off ActiveX controls for all Web sites and then turn them back on selectively as you see fit. While ActiveX controls like Adobe Flash are important for Web experiences today for videos and more, some consumers may want to limit how they run for security, performance, or other reasons.
Administrators can deploy ActiveX Filtering for their organizations easily by setting a group policy. The feature is disabled by default for the Local Intranet Zone so that intranet Web sites and LOB apps can continue to use ActiveX controls without disruption, and can be adjusted separately for each security zone.
