How to Disable Windows Defender SmartScreen on Windows 11

If you remember, Microsoft introduced a new security app for Windows 10 users called Windows Security. Windows Security is also available for Windows 11, and it protects you from both known and unknown security threats.

Windows security is a free security program provided by Microsoft for Windows users. The Windows Security app runs in the background and protects your computer from various security threats such as malware, viruses, ransomware, phishing attacks, etc.

It also has a security feature called Windows SmartScreen which many users don’t know. The role of a Windows SmartScreen is to prevent unrecognized apps from starting and running on your Windows 11 system.

What is Windows SmartScreen?

SmartScreen is a security feature introduced in Windows 8, but it has been improved in Windows 10. SmartScreen acts as a filter that gets your download files checked against a Microsoft Database.

So, when you download something malicious from the internet and attempt to run it, the SmartScreen filter checks it and blocks it. When it blocks a program from running or making changes to your system, you will see a prompt like this.

Although the feature is excellent, sometimes it blocks safe app use. The only way to run the blocked apps is by clicking on the More info > Run Anyway option.
