I have been trying for the last few months, posting and searching.... I can get the unattended install... install with hidden pages.... How can i get XP to "Upgeade" using the same file... All attempts are failing... I looked at Microsoft and they are no help, just more confusion. When i called they asked for cd key and stuff and since i don't have access to the VLK account for tech support, they won't even answer if it can be done. I hope one of the Geniouses here can help... Would also like to do the same with 2K3 server (all three versions) . Like i said i can make a full unattended, Hidden Pages versions and they work fine.... Just need help with upgrading...
