This policy setting allows configuration of Microsoft Defender SmartScreen and whether potentially unwanted apps are blocked. The recommended state for this setting is Enabled. Rationale: Windows Defender SmartScreen can block unwanted apps that will help inform and protect users from vulnerabilities related to adware and low-reputation apps. Impact: Microsoft Defender SmartScreen will block potentially dangerous apps. This could stop the user from installing an app that could be potentially harmful to the system.
To establish the recommended configuration via GP, set the following UI path to Enabled Computer Configuration\Policies\Administrative Templates\Microsoft Edge\SmartScreen settings\Configure Microsoft Defender SmartScreen to block potentially unwanted apps Note: This Group Policy path may not exist by default. It is provided by the Group Policy template MSEdge.admx/adml that can be downloaded from Microsoft here. Default Value: Not Configured - But the user can change this setting.
