This pack is designed to bring a Windows XP CD with SP2 integrated fully up to date with all of the latest hotfixes released by Microsoft since SP2's release. It accomplishes this task via direct integration, where files on the CD are directly overwritten by the updated files.
This is THE best way to slipstream your XP install point/CD to the latest patch level.
This is the way Microsoft should have implemented hotfix slipstreaming. Works great with nLite.
Latest release ads the January patches.
