How to Turn Off or Disable SmartScreen Filter in Windows 11/10

Is your SmartScreen Filter turned off? Оr do you get the message SmartScreen Filter cannot check this website? If that is so, this post will show you how to enable or disable SmartScreen Filter on Windows 11/10/8/7 using the UI, Group Policy or Registry Editor.

For those who don’t know what SmartScreen is, it is a feature that helps detect phishing websites, and can also help protect you from installing malicious software or malware. So whenever you encounter a suspicious site, a warning will be displayed on the browser window to notify the user about the site’s nature and whether the user trusts the site owner/publisher to continue further on the URL provided.

Enable or Disable SmartScreen Filter

Now let us see how to enable or disable the SmartScreen Filter on Windows 11/10 using the UI, Group Policy or Registry Editor.

Turn on or Turn off SmartScreen Filter using UI

Via Windows Security

You can open Windows Security > App & browser control. To turn it off for Apps, under Reputation-based protection, you will see the following 3 options:

• Check apps and files
• SmartScreen for Microsoft Edge
• SmartScreen for Microsoft Store apps.

You can toggle the switch to the On or Off positions as required.

Do note that when you do this, you leave your computer vulnerable.

Via Microsoft Edge

Open Microsoft Edge browser > Settings > Privacy & Services.

Here toggle the Microsoft Defender SmartScreen switch to the Off or On position as required.

Via Internet Properties

You can also open Internet Options/Properties. Go to the Advanced tab and scroll down for Security Category. There if you want to enable/disable the feature, you can accordingly check the box captioned “Enable SmartScreen Filter” then press OK.

Now after you enable the feature, every time you encounter a suspicious URL it will display a message.

If you don’t want to use this feature, you can just uncheck the checkbox to disable the same, but it’s highly recommended since phishing attacks are increasing day by day, increasing the potential threat to confidential information of email accounts.

TIP: You can also quickly bypass SmartScreen filter and download files, without turning off SmartScreen Filter.
