I have something I am stuck on this morning, I have several machines I need to upgrade from windows xp pro to windows 7, each machine came with windows XP loaded on it and with a Windows 7 disc for use to upgrade however the windows 7 discs are full version and not upgrade. when attempting to install it completely formats the machine and installs 7 from scratch. I need to upgrade! Is there anyway that anyone would recommend doing this? I can't lose the users files or the system setup/state. How can I go about upgrading without losing everything?? Any ideas?
