I didn't modify even a single file in the OS. Then I tried with untouched edition of windows 7 Ultimate, and then installed the SP1 it got installed properly but when I try to sysprep everything was going to smoothly till restart in Audit mode and then when I check generalize option and shutdown I got a fatal error. Then I tried to delete vlite registries and tried again but didn't work. Primarily I tried with my already trimmed Ultimate DVD but unable to update, as the sp1 update was not showing.

I have read many threads and posts here saying that reverse integration is better than slipstream for creating SP1, so I have decided to create a SP1 DVD by reverse integration.
