How to Disable SmartScreen on Windows 11: A Step-by-Step Guide

By / September 25, 2025

Summary of Key Takeaways

  • SmartScreen is Microsoft’s built-in protection that blocks suspicious apps, files, and websites.

  • You can disable it via Windows Security settings, Group Policy, or Registry Editor.

  • Turning off SmartScreen reduces security, so only do it temporarily or for trusted apps.

  • SmartScreen settings can be controlled separately for apps, Microsoft Edge, and Microsoft Store.

Introduction

Have you ever tried installing a program or opening a file on Windows 11, only to see a warning like “Windows protected your PC”? That’s SmartScreen at work.

SmartScreen is a useful security feature that checks downloaded files and apps against Microsoft’s database of known threats. But sometimes, it can be too strict—blocking safe programs, custom scripts, or apps from smaller developers.

In this step-by-step guide, we’ll show you exactly how to disable SmartScreen on Windows 11, using multiple methods.

⚠️ Important Warning: Disabling SmartScreen removes an important layer of protection. Only disable it temporarily and always re-enable it after installing trusted apps.

What Is SmartScreen in Windows 11?

SmartScreen (also called Windows Defender SmartScreen) is a cloud-based protection tool that:

  • Checks apps and files for known malware.

  • Warns against phishing websites in Microsoft Edge.

  • Blocks suspicious apps from the Microsoft Store.

It works silently in the background but may sometimes block safe apps you want to run.

Reasons to Disable SmartScreen

  • You’re installing software from a trusted source that SmartScreen falsely blocks.

  • You need to run custom scripts or developer tools.

  • You want to prevent SmartScreen prompts during software testing.

  • SmartScreen interferes with gaming or performance-heavy apps.

Method 1: Disable SmartScreen via Windows Security Settings

This is the easiest method for most users.

Steps:

  1. Press Windows + I to open Settings.

  2. Navigate to: Privacy & security > Windows Security > App & browser control.

  3. Under Reputation-based protection, click Reputation-based protection settings.

  4. Turn off the following options:

    • Check apps and files

    • SmartScreen for Microsoft Edge

    • SmartScreen for Microsoft Store apps

👉 Once disabled, Windows won’t block apps or downloads with SmartScreen.

Method 2: Disable SmartScreen via Group Policy Editor

If you’re using Windows 11 Pro or Enterprise, you can control SmartScreen using Group Policy.

Steps:

  1. Press Windows + R, type gpedit.msc, and press Enter.

  2. Navigate to:

    Computer Configuration > Administrative Templates > Windows Components > File Explorer

  3. Find Configure Windows Defender SmartScreen.

  4. Double-click it → Select Disabled → Click Apply > OK.

  5. Restart your PC.

👉 SmartScreen will no longer run system-wide.

Method 3: Disable SmartScreen via Registry Editor

For Windows 11 Home users (no Group Policy), the Registry method works.

Steps:

  1. Press Windows + R, type regedit, and press Enter.

  2. Navigate to:

    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System

  3. Right-click → New > DWORD (32-bit) Value.

  4. Name it: EnableSmartScreen.

  5. Set Value data = 0.

  6. Restart your computer.

⚠️ Be cautious—incorrect registry edits can cause system issues.

Method 4: Disable SmartScreen in Microsoft Edge

If SmartScreen is bothering you only in Edge:

Steps:

  1. Open Microsoft Edge.

  2. Click the three dots (⋮) → Select Settings.

  3. Go to Privacy, search, and services.

  4. Scroll to Security → Turn off Microsoft Defender SmartScreen.

Method 5: Temporarily Bypass SmartScreen for a Specific App

If you just need to bypass SmartScreen for one program:

Steps:

  1. When the “Windows protected your PC” message appears, click More info.

  2. Select Run anyway.

  3. The app will launch without disabling SmartScreen entirely.

👉 This is the safest option for occasional use.

Pros and Cons of Disabling SmartScreen
