Instead of getting sidetracked into a copyright infringement debate (which I have no intention of doing), I would like to rephrase my question. Does anyone know of any problems using an OEM WinXP Setup disc as a source for installing Win XP onto another manufacturer's system? Again, I am not using my OEM license on any other system than the one it originally came with, merely using the Setup files (+ any Hotfixes I find prior to building) as a Source to facilitate a much reduced System Setup time. It is very annoying running this WinXP sp2 Setup, having to go thru the 2 (more?) reboots that entails, then going to Windows Update and having to install 2-3 packages as separate updates (sp3, ie8, netfx - with reboots between each), then having to go back to Windows Update and actually start the process of installing the 90+ updates that have been released since sp3 (which usually entails at least 2 more passes & reboots thru Win Update). This process currently entails 2-4 hours to just get the Operating System installed & updated and ready to add other software. Under my tests so far (on my Dell systems) with an updated (unattended) source, it is down to about an hour (maybe a bit less) for the OS to be fully installed and up to date.
