Does anyone know, where Win 8.1 gets the icons, used in the dialog, from?
In my case an app icon is corrupted (instead of mine, another app icon is used for my app), and I want to debug the issue. But for that I have to know, where is a source of the icons.
I've already inspected my .exe file resources, there is no other icons there but mine.
It turns out, that when an app is registering itself as matching some user's model, it should set the logo and background color. See AppUserModelId (http://msdn.microsoft.com/en-us/library/windows/desktop/dd378459%28v=vs.85%29.aspx) for details.
