Source: http://www.microsoft.com/technet/prodtechn...y/oempreac.mspx If the above is true, would'nt one just need to add this file, along with the OEMBIOS files, inside each manufacturer's folder, enter the correct keys for each, and let oemscan copy over the oobeinfo.ini which would'nt require any physical key changes? Or have i totally got this confused ? Does oemscan copy over anything you place inside the folders to system32 or will it only look for the four oembios files? You' re right, this works. Thats the method I used all the time, BTW. Of course this needs the Windows Welcome page to be displayed and used so not 100% unattended automation. But I like it to make some individual changes to a system after the whole process, especially for entering the computer name and user name.
