Ok, sorry if this was discussed already or if these are stupid questions, but here goes nothin': I have just began to work with unattended installs of xp and otehr software. I read through all the tutorials on msfn (beginner, intermediate and advanced), and I am just confused about a few things... (i apologize if these are n00b questions) 1. what is the difference between cmdlines and svcpack? 2. Is svcpack used only to install xp hotfixes? or can it be used to install other software as well? If so, is it supposed to call another batch file to run the installations? (Sorry, I understand how cmdlines works, but SVCPACK confuses me for some reason, so if someone can explain it a little further that would be great). 3. Can I get some users opinions about which they use and for what? cmdlines.txt, svcpack.inf, RunOnceEx? Right now I have Office 2003 set to install at cmdlines.txt, it calls a batch file which calls the office installation and others. Is this correct? Or is the svcpack.inf or runonceex method better for office (and otehr apps)? 4. Can someone quickly explain Xplode... is it a replacement for RunOnceEx? (this question is not that important right now, I want to get the basics down first, but a quick explanation would be nice) If anyone can help with the above, I would appreciate it! thanks, atomic.rabbit
