All, I have a fully unattended build that is working well, I now come to the point where I want to add Microsoft security updates, I could slipstream them but that is a management overhead, so I want to use my WSUS server. I have seen a script and in fact I have one that does call the WSUS and install patches, however when I watch an unattended build you will see a section saying "Installing Updates" so my question is can I populate a field in the XML to call my WSUS server?
