Thank you for all the help!!! I successfully integrated/slipstreamed SP3, all relevant hotfixes and updates, IE8 and WMP11 into my XP Pro CD. A few questions: Should I also include the .NET framework 2.0, 3.0, & 3.5? (If yes, how do I accomplish this?) And, Some updates and hotfixes appear in the 'Add or Remove Programs' window as updates even though they were installed at the point of the Windows install, why would this be? The updates appearing in the 'Add or Remove Programs' window are: KB898461 KB2524375 KB941569 KB2508272 KB2443685
