Overview​

This script stops Microsoft Defender SmartScreen from making DNS requests.

By default 1 2, Microsoft Defender SmartScreen sends DNS requests 1 2 to identify potentially harmful websites, like those involved in phishing or malware 2 3.

Disabling DNS requests stops SmartScreen from obtaining IP addresses 1 2, which enhances privacy by reducing IP data sharing. This script also improves security by reducing dependence on DNS servers. Disabling DNS requests mitigates a security risk: if DNS fails to resolve a website, the browser cannot isolate it through Web Isolation 2 3. The Center for Internet Security (CIS) recommends this action for its security benefits 2. Additionally, disabling DNS requests can improve system performance by reducing processing workload. However, this change may reduce IP-based protections 1 2, posing a security trade-off.

This script applies only to Windows devices within a Microsoft Active Directory domain or managed in similar way 2 3. It is effective only on computers under organizational management, such as those in workplaces or schools. It's not applicable to personal computers that are not managed by an organization.

This script configures the SmartScreenDnsRequestsEnabled policy 1. Changes will take effect after restarting the browser 1.

Caution
  • This will display the message "Your browser is managed by your organization" on the settings page.
  • Disabling SmartScreen may reduce your protection against phishing and malware.
  • Disabling DNS requests may prevent the browser from blocking harmful sites by not checking their IP addresses.
