XP SP2 Update Pack Download
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.
