Hi there , well i could use some help over here because i don't exactly know if i am doing right or wrong! Maybe its because of the many ways but anyway i followed the Tutorial Creating a Unattended Windows Xp CD. Which is very helpfull and very handy but there are some little differences that i don't understand or that are not explained in the tutorial Well this is wat i got from now on : I created a winnt.sif without GUIRunOnce because i am going to use RunOnceEx I copied the example that was shown in the tutorial ->RunOnceEx.cmd Well there are commands that are linking to the prepare.cmd and cleanup.cmd , i created those and copied the example as well. I'll have to edit them later because i am going to use other software and yes ofcourse there are new versions of software. Well how do i know when i have to use a cleanup.cmd because in the example there's only a command linking throw cleanup.cmd in the end of the script.... And how do i have to use cmdlines ? because in the example there is only a link throw RunOnceEx.cmd. I could use it like that and edit RunOnceEx? Thats all ?
