Remediation:

To establish the recommended configuration via GP, set the following UI path to Enabled: Warn and prevent bypass :

Computer Configuration\Policies\Administrative Templates\Windows Components\Windows Defender SmartScreen\Explorer\Configure Windows Defender SmartScreen

It is provided by the Group Policy template WindowsExplorer.admx/adml that is included with the Microsoft Windows 8.0 & Server 2012 (non-R2) Administrative Templates (or newer). Note #2: In older Microsoft Windows Administrative Templates, this setting was initially named Configure Windows SmartScreen , but it was renamed starting with the Windows 10 Release 1703 Administrative Templates.

Impact:

Users will be warned before they are allowed to run unrecognized programs downloaded from the Internet.

Default Value:

Disabled. (Windows SmartScreen behavior is managed by administrators on the PC by using Windows SmartScreen Settings in Action Center.)
