How to Disable SmartScreen Filter in Windows 8 and Later?

"SmartScreen" filter was introduced by Microsoft in Internet Explorer 8 (IE8) web browser. It was developed to provide better security to IE users. SmartScreen filter automatically checks websites and files for malicious content and warns you if it finds something suspicious. SmartScreen filter is also present in IE9 and IE10 versions.

Microsoft has implemented the same mechanism in its latest OS Windows 8. Windows 8 comes with SmartScreen filter enabled by default. If you try to run a downloaded program from Internet, it checks the file and if it finds an unrecognized app, it blocks the program and shows following message on screen:

Windows protected your PC

Windows SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.


If you click on OK button, the program execution is terminated. If you are sure that the program is safe, you can click on "More info" link given in the message and it'll provide 2 buttons: "Run anyway" and "Don't run".


You can click on "Run anyway" button to launch the program.
