Introduction
SmartScreen Defender is a security feature in Windows 10 designed to protect your PC from potentially harmful software, websites, and downloads. It uses a reputation-based system to warn you about potential threats and block suspicious content. However, there may be situations where you need to turn it off temporarily or permanently.
Before we dive into the methods of disabling SmartScreen Defender, it’s important to understand the implications of doing so. Disabling this feature can make your computer more vulnerable to malware and other security threats. Therefore, it’s crucial to exercise caution and only disable SmartScreen Defender when you have a specific need, such as running a trusted application that’s being flagged as a potential threat.
In this article, we’ll discuss three methods to disable SmartScreen Defender, but keep in mind that it’s generally recommended to use these methods sparingly and re-enable SmartScreen Defender when your need is met.
Method 1: Disabling SmartScreen Defender via Windows Security
The easiest way to disable SmartScreen Defender on your Windows 10 PC is through the Windows Security settings. Follow these steps to temporarily disable SmartScreen Defender:
- Open Windows Security: You can access Windows Security by clicking on the Windows Start button, typing “Windows Security” into the search bar, and selecting the app.
- Navigate to App & Browser Control: In the Windows Security app, click on “App & Browser Control.”
- Change SmartScreen Settings: Under the “App & Browser Control” section, you’ll find “Check apps and files.” Click on “Reputation-based protection settings.”
- Disable SmartScreen Defender: Here, you can toggle off “Check apps and files” to temporarily disable SmartScreen Defender.
Remember that this method will only temporarily disable SmartScreen Defender. It will be automatically re-enabled after a certain period.
Method 2: Using Group Policy to Disable SmartScreen Defender
For more control over SmartScreen Defender, you can use the Group Policy Editor. This method allows you to disable it more permanently. However, please be cautious when modifying Group Policy settings, as it can affect other aspects of your system. Here’s how you can do it:
- Open Group Policy Editor: Press
Win + R
, type “gpedit.msc,” and press Enter to open the Group Policy Editor. - Navigate to Windows Defender SmartScreen: In the Group Policy Editor, go to “Computer Configuration” -> “Administrative Templates” -> “Windows Components” -> “Windows Defender SmartScreen.”
- Edit Windows Defender SmartScreen settings: Look for the policy named “Configure Windows Defender SmartScreen” and double-click on it.
- Disable Windows Defender SmartScreen: In the policy settings, select “Disabled” and click “OK” to save the changes.
This method will effectively disable SmartScreen Defender. However, if you ever need to re-enable it, you can follow the same steps and set the policy to “Not Configured” or “Enabled.”



Method 3: Modifying Registry Settings to Disable SmartScreen Defender
Modifying the Windows Registry is a more advanced way to disable SmartScreen Defender. It offers a high degree of control but comes with a warning: editing the registry can cause serious issues if done incorrectly. If you’re not experienced with the Windows Registry, it’s advisable to seek assistance from someone who is. Here’s how to proceed:
- Open Registry Editor: Press
Win + R
, type “regedit,” and press Enter to open the Windows Registry Editor. - Navigate to Windows Defender SmartScreen: In the Registry Editor, go to
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System
- Create a DWORD Value: Right-click on the “System” folder, select “New,” and choose “DWORD (32-bit) Value.” Name it “EnableSmartScreen.”
- Disable SmartScreen Defender: Double-click on the “EnableSmartScreen” entry, set the value to “0,” and click “OK” to save the changes.
Again, please be extremely cautious when modifying the Windows Registry. Editing it improperly can lead to system instability.
