How to Disable SmartScreen Filter on Windows
Today I will talk about Windows SmartScreen Fliter and how to disable SmartScreen Fliter.
What Is a SmartScreen Filter
SmartScreen Filter is a Windows security feature that helps to protect the computer from downloading unrecognized and unsafe applications or installing malicious programs.
Though the SmartScreen Filter is such a security layer built into Windows OS, like Windows 10, 8, 7, etc., you may not like the annoying warnings when you are sure what you are installing or running is safe to Windows. If you don’t like such Windows feature, here I will introduce to you how to disable SmartScreen Filter on Windows OS.

How to Disable SmartScreen Filter on Windows 10, 8, 7, Vista, XP
There are different ways for different Windows OS to disable SmartScreen Filter, and you can choose one adapting to your Windows OS.
Note: You’d better back up drivers, documents and other important data before the system changes. It is also recommended to create a system restore point in case any issues like graphics error, MSVCP110.dll missing error, etc. occur.
