oem is original equipment manufacturer. in my registry the product key is not what is on my coa. so it must be a volume licensing key that has been allotted dell from microsoft.
I have used my dell xp pro install disk (slipstreamed with sp3) to install xp pro on other dell pc's, I use my cd and their product key from their coa.
