Made a little proggy that allows you to change what programs will be installed at runonceex in gui-setup at 39th min (detached program) ok to make this work you need to do the following..... create a directory "Install" in your $OEM$\$1 (ie $OEM$\$1\Install) put the files from the unattended.zip and also a default RunOnceEx.cmd in the Install folder create a directory "Setup" in your $OEM$\$1 (ie $OEM$\$1\Setup) put sol.exe , freecell.exe , winmine.exe from your windows into this folder (the program will launch the game of your choice to play after you close it :-)) add the following line to your winnt.sif [GuiUnattended] DetachedProgram="%systemdrive%\install\unattended.exe" and in your $OEM$\cmdlines.txt put a cmd file RunOnceLoader.cmd in the $OEM$\RunonceLoader.cmd %systemdrive%\Install\RunOnceEx.cmd Thats it.... btw - i had to do the tricky extra cmd file for the cmdlines.txt cause it does not seem to like having %systemdrive% in there but works fine to a cmd in local dir the ini file has some help stuff in it for how to make it work and has my setup i have on my current dvd i'm working on so you should be able to figure out the syntax unattended.zip
