I've just started using Windows ICD, wanting to create an image for our company computers. I've configured the user accounts and added drivers and other custom settings but would like to see if I can also add in applications to get installed as well. I'm planning using the option to create a bootable USB for the image. Exploring the "Applications" section in ICD, I see that it is requiring a .appx file (Application Package) and after googling that, I haven't found much on how to create one, tied to using Windows ICD. These would be simple applications that I'd want to install (all are executables). Are there instructions on doing this? or is it possible the way i'm wanting to do this?

Thanks.
Bill.
