NOTE: Microsoft is ending support for Service Pack 2 on the 13th July 2010. So, I've decided the time has come to retire my SP2 pack. I will continue to maintain my SP3 pack for as long as I can. To use my SP3 pack, first slipstream SP3 and then my SP3 Update Pack using nLite.
You'll want nLite to slipstream my update pack and addons into your xp cd, see nLites website for download and usage instructions, it can do so much more than just slipstream stuff so you might want to give the guide a once over ;)
NOTE: nLite v1.4.9 is the minimum version required to integrate this pack.
You can get support for the current update pack in the forums.
