As I mentioned before, my company stopped selling Vista so I never worked with SP2. However, when I wanted to make SP1 installs, here was my process. 1. Use Autounattend.xml to install Vista and have it boot to Audit mode. 2. Install the SP1 standalone installer (wave0 in my case) 3. Sysprep /oobe /generalize /shutdown 4. capture the drive as a WIM with Imagex Of course I used a WDS Server for my deployments, but you can create a new install DVD easily. Take your WIM and call it INSTALL.WIM and replace the one in the sources folder. You should be able to do an install with that, probably can do with an XML as well. You do not need to put the XML on the DVD, you can insert a UFD during install.
