I want to quickly select what software is to be included from a library on my pc, and leave the original xp uncluttered. And automatically generate a menu to be run during installation, preferably at t-39. And without having to worry about creating cabs. So when I add something to my library i just copy the installation folder and add an xml file that describes what to run - perhaps something must be done at one stage (registry?) and something else at another, like guirunonce. Now if I already had made a previous iso i would reopen this project and tick the new software if i wanted to include it, then choose if this is to be optional or not (visible at menu). I'm not sure if UnattendXP let me do this, it looks kinda complicated. Maybe my project would only be useful if you create multiple versions of an iso.. one for dad, one for mom, one based on Pro, one on Home, etc.. I have only made unattended xp isos manually so far, but I don't like working directly in the xp source, or having to copy it from a clean one when i start a new project.
