Man, "if you are not using Apply...button..then your ISO will contains all edition with Vista Ultimate Edition with SP1" This was what I wanted to know. I don't care about my ISO contains all edition, but I want have Ultimate with SP1. Then I guess the way that I done is correct. The informations that vLite show is: Operation System: Windows Vista ULTIMATE Description: Windows Vista Ultimate Architecture: 32-Bit Version: 6.0.6001.18000 vLite: v1.1.6 RC (26/04/2008 04:40:17) I didn't find any information about Service Pack 1 but I found differents informations between Ultimate and the other versions: Version: 6.0.1.6001.16386 and the vLite information don't have in other versions only in Ultimate version. Thanks Matiello
