In order to install SP3 on a running system, it needs to be at least SP1; however you can slipstream SP3 onto a a gold (RTM) XP source just fine. I'm not sure about the "Cleaner" part--I've slipstreamed into an XP SP2 disk and it works just fine. Is there anyone that slipstreamed SP3 onto a SP1 disk install? Reason I ask is I reloaded SP1, went to the MS update page and they said I should upgrade to SP2. Obviously, SP3 isn't an option until SP2 is installed. It made me think I should first S/S SP2 and S/S SP3 onto that result.
