Cool, thanks for the info. So I will definitely have to remove things to slipstream SP1, or just if I want to add the patches afterward too? I don't really want to remove anything unless I have to, but I don't want to spend forever installing patches. Will vLite grab the hotfixes from my computer or do I have to download all the installers from Microsoft? That might be a pain. By base OS, you mean I have to make the image on the 64 bit computer, right? I just remembered thankfully that the DVD writer in this machine is a bit broken, and I don't want to risk burning a bad OS disk with this one so I'm going to have to copy the image to my laptop over LAN and burn it from that most likely. Can I do that?
