One point of clarification... My understanding is that SP1 installation is heavily dependent on all prior hotfixes having been installed. The instructions though don't mention the need to incorporate any hotfixes into the ISO (in fact they specifically state NOT to enable components, etc.). Do I understand correctly that with slipstreaming ONLY the initial Vista installation files and SP1 are needed and the hotfixes can be ignored? (In case it matters, I'm installing Vista Business.) Thanks in advance to anyone who can provide a prompt reply.
