Hey, I did solve the problem. I shall post the XML file I used as soon as I find it. Should note, that this is ALL I wanted the install to do, so it's a very simple xml file. Should be noted the problems that come with doing this aren't well documented... First of all, the warning on 'upgrades'. By upgrades they mean moving from Home Premium to Ultimate for example. Windows Updates will still work but it also has problems, basically, some updates won't install, the solution is to create a copy of the users directory structure on C:\ (where you windows installation is) (temporary) you then delete this structure when the updates are installed. You only run into problems like this with a couple of windows updates, but they are important updates, and will cause all the other updates that follow to 'apparently' fail. Find the problematic update and try to install the updates one by one until all updates except the problematic one have installed.
