[SOLVED] Windows Defender SmartScreen prevented an unrecognized app error

What is SmartScreen?

SmartScreen is a security feature built into Windows 10, specifically the Windows Defender tool.

Each time an application is ran Windows 10 will check if it is a “good” application against their catalog of applications.

It’s a good security measure and is particular helpful at stopping malware spreading through email attachments – where some users do not understand the difference between a legitimate document and an application.

Why has SmartScreen prevented my application?

Either it’s a known bad or unknown application.

Sometimes SmartScreen will prevent applications you know are not bad – for example, it’s a CMD or VBS script you wrote, or a program from a trusted source.

How do I run an application SmartScreen has prevented?

If you’re absolutely sure you can trust the application you can run it by

  1. Click on the ‘More info’ link
  2. Click on the ‘Run anyway’ button.

How do I completely disable Window Defender SmartScreen?

This is NOT recommended.

  1. In the taskbar, search for “App & browser control” and click on it when it appears in the search results
  2. Under ‘Check apps and files’ select ‘Off’
  3. Click ‘OK’ when prompted to apply the changes.

Is SmartScreen a privacy issue?

Much like anything in the Windows 10 environment – privacy is … secretive which means it’s lacking.

Microsoft have said that they are not keeping personally identifiable information such as your IP address – but they do collect it when communicating with their online system.

Personally, I think the security benefits of SmartScreen out way the privacy issues – and even if you were to disable it, Windows 10 is like a leaking sieve when it comes to privacy. If privacy were a concern I would consider an alternative operating system.
