SmartScreen Filter in Windows 10


SmartScreen Filter in Windows 10 protects your system from web-based attacks such as phishing, malicious software downloads and drive-by attacks. The filter is built into OS and integrated into Microsoft browsers: Microsoft Edge and Internet Explorer 11.

Filter is based on the cloud ranking system from Microsoft, which inspects and evaluates each site you are visiting (URL reputation checks) and all downloaded/executable files (Application Reputation protection). Filter analyze and compare information about a file or website with an existing list of malicious sites and files in database. If file is marked as unsafe or it is not available in the rating base, file downloading or execution will be blocked by SmartScreen Filter.

So, when you will try to download unknown file using IE or Edge, it will be blocked and user will be alerted in that case.

This unsafe download is blocked by SmartScreen Filter:

If the executable file was downloaded using a different browser or it was copied from another computer, the filter will trigger when you will try to run the file and block its launch.

Tip. One of the drawbacks of the SmartScreen Filter is blocking most of the applications that are not digitally signed.

SmartScreen Filter in Windows 10 is enabled by default, but Administrator can change its settings or turn it off completely. Now let’s take a look on how we can change SmartScreen Filter settings.
