Specify use of ActiveX Installer Service for installation of ActiveX controls
Supported on At least Internet Explorer 8.0
What it does
This policy setting allows you to specify how ActiveX controls are installed. If you enable this policy setting, ActiveX controls are installed only if the ActiveX Installer Service is present and has been configured to allow the installation of ActiveX controls. If you disable or do not configure this policy setting, ActiveX controls, including per-user controls, are installed through the standard installation process.

These deployment candidates come from the ADMX template; they are separate from the native CSP mapping above.
- The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
- Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
