hey guys we often repair windows installations when changing motherboards or IO subsystems in servers or client-class machines. i was wondering if it was possible to fully automate this procedure? (start the installation, push enter to install windows (not R for recovery), it'll detect the old version of windows at which point you push R to repair it. is this possible to do? i posted this question in some microsoft support forums and it was suggested to me to try NTUpgrade=Yes, however that seems to do nothing. we will be using this for both XP and 2003 server any information that you have would be very much appreciated thanks
