Hai wimb, Thanks for ur wonderful share. I have created winpe3_x86.iso using make-pe3.exe and tested in USB drive. The OS was booted successfully. I have changed the network from dynamic to static in the OS and then I rebooted the OS. When the OS loads again, the changes I have done was not present. and only the original settings was present. I realized it was because, the OS loads from RAM so the settings are not saved in registry. I want to save the changes that made in the OS after reboot. Can you tell please how this can be achieved?
