Ensure 'Prevent bypassing Windows Defender SmartScreen prompts for files' is set to 'Enabled'


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

The recommended state for this setting is: Enabled.


SmartScreen will warn an employee if a file is potentially malicious. Enabling this setting prevents these warnings from being bypassed.


Employees will not be able to ignore SmartScreen Filter warnings on files, and they will be blocked from downloading unverified files (that are potentially malicious) that SmartScreen detects.


To establish the recommended configuration, set the following Device Configuration Policy to Enabled:

To access the Device Configuration Policy from the Intune Home page:

Click Devices

Click Configuration profiles

Click Create profile

Select the platform (Windows 10 and later)

Select the profile (Custom)

Click Create

Enter a Name

Click Next

Configure the following Setting

Name: <Enter name>
Description: <Enter Description>
OMA-URI: ./Device/Vendor/MSFT/Policy/Config/Browser/PreventSmartScreenPromptOverrideForFiles
Data type: Integer
Value: 1

Select OK

Continue through the Wizard to complete the creation of the profile (profile assignments, applicability etc.)

Note: More than one configuration setting from each of the Configuration profiles (ex: Administrative Templates, Custom etc.) can be added to each Device Configuration Policy.

Default Value:

Disabled. (Employees will be able to ignore SmartScreen Filter warnings about unverified files and continue the download process.)
