The SmartScreen filter built into Windows automatically scans applications, files, downloads, and websites, blocking known-dangerous content and warning you before you run unknown applications. You can disable it, if you like.

Should You Disable SmartScreen?

We recommend you leave SmartScreen enabled. It provides an additional layer of security that helps protect your PC, whether you’re using antivirus or not. Even if SmartScreen automatically blocks an unknown application you know is safe, you can click through the warning to run the application anyway.

On the other hand, disabling it may allow a malicious application to slip through the cracks.

How to Disable SmartScreen on Windows 10

SmartScreen settings are located in the Windows Security Center interface. Open up the Start menu, then search for and open “Windows Security.”

Click the “App and Browser Control” icon in Windows Security to find these settings.

• Then click on “Reputation-based Protection Settings.”
• There are four different Windows SmartScreen options, and you can disable them individually.

The “Check Apps and Files” option controls the operating system’s SmartScreen filter, which protects you no matter where you download files from. When you try to open a downloaded application or file in File Explorer or another application, Windows will check that application or file and block it or display a warning if it’s unrecognized.

• You can also control whether or not Windows Security will block potentially unwanted software. You can disable it completely, or you can set it to block apps or downloads individually.
• The “SmartScreen for Microsoft Edge” option controls the SmartScreen filter build into the Microsoft Edge browser. It blocks malicious websites and downloads, but only in Microsoft Edge.
• The “SmartScreen for Windows Store apps” filter is used when apps you download from the Windows Store access web content. It warns you before those apps load dangerous content.

Disable SmartScreen on Windows 8

• On Windows 8, you’ll find this option in the Control Panel. Navigate to Control Panel > System and Security > Action Center.
• Expand the “Security” section, locate Windows SmartScreen in the list, and click “Change settings” under it.

You can then choose what Windows does with unrecognized programs. You can have Windows require administrator approval before running an unknown program, warn you without requiring administrator approval, or select “Don’t do anything” to turn off Windows SmartScreen.
