You can find enough info in the Unattended CD Guide on this site to do a runonceex setup. If you are using the guirunonce method. It is not so painful to convert to runonceex method. I would advise it, since you are doing a dvd. You just need cmdlines.txt to run your batch file, witch inserts entries into the registry, so the registry will execute your software installs at the end of setup. One of the 1st entries can be something like your start.cmd, with will remove the wallpapers etc. that you do not want on the hardrive. Then software will be installed from the dvd.
