[pspcracka]

alright im making my own custom OS of windows server 2003. first how do i enable themes when its still in the iso form. i know it has to be a reg file but i dont know what to do next

2nd i have a bunch of windows sounds i want to include. i already replaced the old sounds with the new (both the cab and file are the same name as the origional ones) but again i have to enable sounds and select the sound theme i want. how do i do this?

please help and dont tell me 2 google it, i already tried.

thanks in advance pspcracka
