Could it be that the application icon that you installed has different images for different icon sizes, and that is why you see the difference in the explorer?
To verify this, open your icon in Visual Studio. Various permissions are listed (on my screen on the left). If you donβt want to create all the permissions, just delete the ones you donβt need and Windows will try to resize the icons for you, although they will appear blocky in a different resolution.
