I want to be able to use a modified shell32.dll, and explorer.exe files in my unattended XP install how do i go about doing this? I have tried putting them in \$OEM$\$$\System32 but when setup goes to the gui part of setup it errors.

in order to put your own modified windows file checker marked files

u'll have to disable the sfc first.. or modify the sfc marked files list which is sfcfiles.dll....

See http://unattended.msfn.org/xp/hacked_files.htm to find out how to prevent Setup from showing a copy error on modified files

Thanks guys!
