For almost 2 years i used HFSLIP for slipstream (after nuhi went on "vacations") and after slipstreaming, used nlite for components removal + config + tweaks. In XP, i had modified the original source reg files with the tweak that makes quicklaunch bar to show in taskbar, disable annoying WGA "update", and few more tweaks that i needed so, everytime i use HFSLIP & nLite i didn't include a regfile to integrate. Do a test, maybe it works much better than "like 'out of the box'" and i say 'maybe' because there are unnofficial updates.
