Hello, This could be a stupid question but I am learning... I have my winXP Pro modified. I only want to include updates and a few registry tweaks. This part is done. I want/need to keep "OemPreinstall" set to "No" in "winnt.sif". Now, I read that if "OemPreinstall" is set to "No", setup will not look in "$OEM$" folder. In "$OEM$" folder I have "cmdlines.txt" for my registry tweaks. So if I understand correctly it will not be copied/parsed/executed. Now my question is - How to add/run my registry tweaks and keep "OemPreinstall" set to "No" ? Is there a way to copy the files so I can launch them with "GuiRunOnce" for example ? Thanks in advance, OJi.
