I have the "imageres.dll" of Windows 8 and Windows 8.1. I did find the backgrounds present in them but I have no idea of how to add them into the Windows 8.1.
Is it possible to get these start screen backgrounds back in Windows 8.1, I don't really like many of the choices available in this updated version.
