An update to add support to wildcard characters for the ActiveX Installer Service (AxIS) in Windows Vista

In Windows Vista, the ActiveX Installer Service (AxIS) lets a nonadministrative user install an ActiveX control in Internet Explorer when the user visits a Website. The ActiveX Installer Service determines whether ActiveX controls can be installed by checking whether the host URL that requests the ActiveX control installation is approved in the ActiveX installation policy for sites in Trusted zones Group Policy setting. This does not apply to the Approved Installation Sites for ActiveX Controls Group Policy setting, as wild cards are ignored. In this manner, administrators can configure the Group Policy setting to control the sites from which a user can install ActiveX controls.

Note For more information about AxIS, including Group Policy settings, go to the following Microsoft Website:

Microsoft has released an update for AxIS. This update enables you to use wildcard characters when you try to add a host URL in the Group Policy setting. This makes it more convenient for you to configure the ActiveX Installer Service.
