The ActiveX Installer action allows an application, such as Internet Explorer, to enable standard users to install approved ActiveX components.
This behavior mimics the ActiveX installer service in Windows Vista, Windows 7 and Windows 8. The ActiveX Installer action allows (or denies) specific ActiveX components to be used by Windows XP users.
When you set up an ActiveX Installer action, you can choose from the configurations shown in the following screenshot.
ActiveX installer actions are used only on Windows XP machines and are reported by the File Inventory "Com Component Inventory" policy, which reports on downloaded ActiveX components.
