XP Slipstreaming – tried nLite – worked well – download here . Allows you to integrate SP3 and other downloaded updates (although I prefer RyanVM for the other post SP3 updates) plus allows removal of unwanted windows components and pre-entry of information to allow for uninterrupted instal. There is also a tool to create add-ons from applications – here – although AVG reports a trojan (falsely) and prevents instal. For  guidance on use of nLite see here
