Basically, Windows SmartScreen is a tool and feature that checks the safety of a file or application that may be harmful on a Windows system. This feature has been integrated since Windows 8. When you run a file or an application of unknown origin, Windows will block this application and display a screen asking whether or not you should run this application.
It can be said that this feature is extremely useful, however, if many of these notifications appear when running the application, it will make many people feel uncomfortable. Therefore, you can proceed to disable Windows SmartScreen on Windows.
What is SmartScreen filter?
SmartScreen acts as an early warning system to let users know if a website or application is suspicious or if the downloaded file is not found in the list of safe software programs. Essentially, SmartScreen uses a large database of whitelisted and blacklisted websites to analyze whether a given thing is safe to open or not.
SmartScreen runs in the background on Windows and will usually show up as a large blue box indicating “Windows protects your PC” (Windows already protects your PC) by blocking a certain program or website. If it's a program, you'll usually have options “Run Anyway”. If SmartScreen appears on a website that you know is safe, you can click “More Information” and report it as a safe website.
Overall, SmartScreen is a useful layer of security that you should leave behind. However, it sometimes prevents you from visiting websites or downloading things that you know are safe, but have not been verified by SmartScreen. At times like these, you should disable SmartScreen.
