Modern apps are blocked by security software when you start the applications on Windows 10

Applies to: Windows 10, version 1903, all editionsWindows 10, version 1809, all editionsWindows 10, version 1607, all editions


When you start a Modern app, such as Microsoft.MSN.Money.exe or Microsoft.Photos.exe, on Windows 10, version 1607, Windows 10, version 1809 or Windows 10, version 1903, you notice that the application is blocked by your security software.


This issue occurs because the individual files within an application package are not digitally signed even though the packages are catalog-signed.


To work around this issue, add the affected applications to the white lists of your security software.
