Prevent bypassing Windows Defender SmartScreen prompts for files

This policy setting lets you decide whether employees can override the Windows Defender SmartScreen warnings about downloading unverified files.

If you enable this setting, employees can't ignore Windows Defender SmartScreen warnings and they are blocked from downloading the unverified files.

If you disable or don't configure this setting, employees can ignore Windows Defender SmartScreen warnings and continue the download process.
