I am so close to completing my perfect unattended XP install cd I can taste it. I have been at this for nearly four months now and today I ran my latest incarnation - everything went really well no critical updates, no recommended updates apart from one wee glitch. My cd is a hybrid of Green Machine's XPCREATE (Indespensable) which I use to slipstream all the hotfixes and MSFN's XP / 2003 CD Guide (A life saver) which I am now getting into deeper to install various apps and reg tweaks post first boot. Also, I have to say that this forum has been such a help and an absolutely fantastic education. So, a huge thanks to everybody for all the knowledge shared here. Anyway, back to my glitch. Today I got a problem at the 13 mins to go stage. A grey window popped up saying something to the effect that I had used an incorrect parameter. Underneath there were a lot of various switches displayed - one of which I expect must have been the correct parameter. Now, I have to admit, I have no idea just what exactly is going on at the 13 mins to go stage but I suspect it may have something to do with the reg tweaks? I say this only because all the apps appear to be instaling fine post first boot. The only other modification I have made to the cd recently was to add WNTIPCFG.EXE into the SVC-X2M folder during the XPCREATE phase. Perhaps this could have something to do with it? Anyway, I attach my reg tweaks file in the hope that someone can find something wrong with it. Thanks in advance. RegTweaks.reg RegTweaks.reg
