If the dvd of vista that I have already has sp1 included, do I still need to follow the SP1 slipstream guide on the forums? Also, I looked around on the forums a bit but I couldn't figure out how to word this question: I have a lot of programs that I want to install automatically after vista installs, and before windows loads. Is the RunOnce program what i want to use? Is there a better way? Or is there a FAQ for using the RunOnce program? Thanks for your time, and feel free to point me in the right direction and lock this post if I'm just blind and didn't see the obvious posts on the forums!
