I'm having some trouble doing this. I figured I was supposed to expand the SP2 Update CAB and remove the files before integration. The problem with that is repacking all the files into one CAB again, I cannot find the cmd to do that.Remove .infs entries in RVMUpPck.inf along with files for these hotfixes:
KB887078, KB888407, KB885353, KB886610
(To determine what files to delete read hotfixes description in RVMUpPck.inf, just hit "ctrl + F")
Delete compressed cats in svcpack folder and remove entries for .cats in svcpack.inf file
I also tried integrating with nLite, and then following the above instructions. Unfortunately I get several errors throughout Windows setup about missing files.
Hope we can clear this up
