Force Microsoft Defender SmartScreen checks on downloads from trusted sources

Computer and userIntune-readySmartScreenForTrustedDownloadsEnabled_recommended

Supported on Microsoft Edge version 78, Windows 7 or later

155.0.4283.62

What it does

This policy setting lets you configure whether Microsoft Defender SmartScreen checks download reputation from a trusted source. In Windows, the policy determines a trusted source by checking its Internet zone. If the source comes from the local system, intranet, or trusted sites zone, then the download is considered trusted and safe. If you enable or don't configure this setting, Microsoft Defender SmartScreen checks the download's reputation regardless of source. If you disable this setting, Microsoft Defender SmartScreen doesn't check the download's reputation when downloading from a trusted source. This policy is available only on Windows instances that are joined to a Microsoft Active Directory domain, Windows 10 Pro or Enterprise instances that enrolled for device management.

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.
