The "App & browser control" page is the place to configure the Windows Defender SmartScreen settings that can help you to protect your computer against sites, apps, and files that may contain malicious code. The default settings are the recommended configuration you should be using. Of course, that is unless you have a specific reason to change them.
- To change the default SmartScreen settings, do the following:
- Open Windows Defender Security Center.
- Click on App & browser control.
- Select the level of protection you want for apps and files, Microsoft Edge, and Microsoft Store apps.
You'll also notice Exploit protection at the bottom of the page. This is an advanced feature that can help to mitigate malware and vulnerabilities without having to wait for a malware or system update.
