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.
