I have several XP images and they all accepted any key I threw at them. Well, except for the upgrade keys, since I was doing a clean install. Let's not go into detail of
where I got the keys, though, OK?
An "Upgrade" CD will even accept any other XP key for the non-upgrade edition... the problem being that most upgrade discs aren't bootable to begin with, so you need an OS to start the install anyway.... but using it you can enter the non-upgrade key (be it VLK or retail) and perform a clean install, an option not available using the "upgrade" key.
Volume License Windows XP Install CD
the thing is- there is no "Volume License" XP install CD- a "Volume license" is issued to manufacturers, Dell, Toshiba, HP and so on so that they may preinstall XP into the PCs without having to go through the standard activation process- they are "preactivated" in a way. "volume license" discs simply aren't produced.
they key word of the title of the link you provided is "OEM Restore Disks"- an OEM restore disc is simply not an XP CD in the general sense- but a recovery Disc. for all intents and purposes it is not a "windows" CD.
