How to Completely Disable ‘SmartScreen’ (Microsoft Defender SmartScreen) for Microsoft Edge via Group Policy in Windows 11

Microsoft Defender SmartScreen is a cloud-based anti-phishing and anti-malware component integrated into Windows 11 and Microsoft Edge. It analyzes websites and downloaded files against a dynamic list of known threats, blocking access if a match is found. While highly recommended for standard users, strict enterprise environments often deploy third-party, deep-packet inspection firewalls, specialized web gateways, or alternative endpoint detection and response (EDR) agents. In these scenarios, having Edge’s SmartScreen enabled introduces redundant cloud lookups, consumes unnecessary bandwidth, and can falsely flag proprietary internal applications, leading to widespread access issues.

This guide explains how to completely disable Microsoft Defender SmartScreen for Microsoft Edge system-wide using the Group Policy Editor in Windows 11, ensuring your third-party security appliances handle all threat filtering.

Disable Edge SmartScreen via Group Policy

To enforce a strict block that prevents the browser from utilizing the SmartScreen service and locks the settings from user modification, we must deploy an administrative template. Note that this requires Windows 11 Pro, Enterprise, or Education editions.

1. Log into Windows 11 with an Administrator account.
2. Press the Windows Key + R to open the Run dialogue box.
3. Type gpedit.msc and press Enter to launch the Local Group Policy Editor.
4. In the left-hand navigation pane, strictly follow this exact path:

   Computer Configuration > Administrative Templates > Microsoft Edge

5. In the right-hand pane, locate the policy named Configure Microsoft Defender SmartScreen.
6. Double-click the policy to open its configuration window.
7. Select the radio button next to Disabled.
8. Click Apply, then click OK.

Verify the Configuration Lockdown

Group Policy changes require the browser to read the registry upon its next launch. Close all active instances of Microsoft Edge.

To verify the restriction is active, reopen Microsoft Edge and navigate to edge://settings/privacy. Scroll down to the “Security” section. The toggle switch for “Microsoft Defender SmartScreen” will be completely greyed out and locked in the ‘Off’ position. A briefcase icon will appear alongside a message stating, “Your browser is managed by your organization.” Edge will no longer intercept file downloads or block URLs based on Microsoft’s telemetry, allowing your enterprise network security stack to operate without interference.
