I've read a lot of topics here and somewhere else...but I'm doubtful. Now I want to make an unattended ISO of windows vista ultimate x64 with SP1 drivers, hotfix and all my favorite applications. So I will be able to install all I need in one step. I've read this guide but I'm doubtful: Do I need other hotfixes besides sp1's ones or this guide is correct ? Does SP1 contain all hotfix I need ? Will I need to download other hotfixes non included in SP1 ? Can I install additional drivers using drivers packs and following the same method I used with nlite? If this method don't work, wich is the correct one ? I've maked applications' cabs for nlite but I'm not sure they will work with vlite. Are they compatible ? How can I add my applications to ISO image ? In short: I need help to make a complete iso image with windows vista ultimate x64, all needed drivers, all needed hotfixes and all my favorite applications. Thanks a lot ! Sorry for my bad english
