18.9.90.3 (L2) Ensure 'Prevent Internet Explorer security prompt for Windows Installer scripts' is set to 'Disabled'

Information

This policy setting controls whether Web-based programs are allowed to install software on the computer without notifying the user.

The recommended state for this setting is: Disabled

Suppressing the system warning can pose a security risk and increase the attack surface on the system.

Solution

To establish the recommended configuration via GP, set the following UI path to Disabled :

Computer Configuration\Policies\Administrative Templates\Windows Components\Windows Installer\Prevent Internet Explorer security prompt for Windows Installer scripts

Note: This Group Policy path is provided by the Group Policy template MSI.admx/adml that is included with all versions of the Microsoft Windows Administrative Templates.

Note #2: In older Microsoft Windows Administrative Templates, this setting was initially named

Disable IE security prompt for Windows Installer scripts

, but it was renamed starting with the Windows 8.0 & Server 2012 (non-R2) Administrative Templates.

Impact:

None - this is the default behavior.
