    Windows Defender SmartScreen


    We are developing an application and singing both the executable/dlls as well as the installer with an EV code-signing certificate. Our application recently we began being flagged by Windows Defender SmartScreen despite having the EV certificate. It passes the Windows App Certification Kit with no warnings or issues related to the digital signature, and the certificate is not expired.

    Defender/SmartScreen warning.

    Though this doesn't explain why an application's specific reputation might have changed, the addition of granular controls for these settings in the recently released Windows 10 Creators Update may have something to do with it.

    Smartscreen in Creators Update

    This newer implementation of SmartScreen within Windows 10 has also been renamed to

    Windows Defender SmartScreen
    rather than the old Windows SmartSreen and SmartScreen Filter name within the browser.

    Again, none of this specifically explains a change in reputation, but it's possible that all of these changes might have affected the reputation for some applications or certificates.

    Since you didn't specify what type of certificate you are using, since this affects the ability to add or gain reputation status more quickly. The

    Windows Defender SmartScreen® Filter Frequently Asked Questions
    page covers this as follows.

    There are industry best practices for application developers that will affect your download's reputation and help ensure reputation is established and maintained. If your program is not digitally signed, reputation cannot automatically be shared
    across different versions and builds.

    To help establish your application's reputation, consider doing the following:

    • Digitally sign your programs with an Authenticode signature

      Reputation is generated and assigned to digital certificates as well as specific files. Digital certificates allow data to be aggregated and assigned to a single certificate rather than many individual programs. Only Authenticode Certificates issued by a Certificate
      Authority (CA) that is a member of the Windows Root Certificate Program can establish reputation.
    • Apply for a Windows Logo

      To learn more visit the
      Windows Logo Program
      page on MSDN.

  4. Windows Defender SmartScreen

    I cannot disable Windows SmartScreen

    Hi,

    Disabling Windows SmartScreen in updated Windows versions was already moved to Windows Defender Security Center. It's a new feature in Windows 10 Creators Update. That might be the reason why it is not showing in the Control Panel. For us to disable the
    Windows SmartScreen, please follow these steps:

    • Click on Start.
    • Type Windows Defender Security Center.
    • Press Enter.
    • Click on App & browser control.
    • You have 3 options:
    • If you will disable it, it will show you a warning message.

    Let us know if you have other concerns.
