Why to boot up bartpe to install winxp ? Well that way you can customize your installation on the fly. i'm not a programmer but i altered Kelsenellenelvian's WPI-Lite a bit to create on c: runonce.cmd. the file i changed is generate.js which located in Wpiscripts folder. i tested it only on winxp, to run WPI on bartpe you probably need a plugin to enable mshta. this is mainly a concept not a fullworking app, so dont ask me why you cant get it work. the main reason i posted it here is to give you all an idea what can be done using bartpe. and maybe someone with more experience in programming will take the lead and give us a fullscale app. more on bartpe & winxp: http://www.msfn.org/board/index.php?showtopic=68252.
