If you boot with this DVD and start one of the setup routines, this will clean install a corporate edition of Windows XP Pro SP3 updated to the month of release. The aim is for you to be able to stick this DVD in, quickly get setup running, and then when setup finally stops, your computer is ready to use. There are no steps in between, you don't need to do a thing, you get a fully unattended installation of everything. This means all your device drivers installed and no critical updates need installing. You just sit back and enjoy the ride.
