    I am trying to use an XP Pro cd key from a genuine unbranded OEM COA, but
    the installation is saying the cd key is invalid. I've tried installing
    using XP Pro OEM with SP1 and SP2, but neither of them would allow the
    installation to accept the cd key. Both disks tried were OEM, and the COA is
    unbranded OEM, so I'm not sure why the cd key is not working. Can anyone
    help?

    Maybe it's a RTM (or SP0) key? The algorithm changed with SP1, so
    RTM keys won't work with a SP1 or SP2 install CD.

    Are you sure you're copying the serial from the COA properly? I
    couldn't get XP to install once - either my brain or my fingers were
    transposing two of the characters each time I entered the serial. Or is
    there a chance that one of the characters isn't clearly printed, and
    you're mistaking it for another? You could always try installing using
    a serial that you know to work, then change it to the one on the COA
    once it's installed and see if it will register.

    Because it is a pre SP1 CD key.

    Workaround:

    Get a dodgy SP1 CD Key. Install using that. Run Activation Wizard.
    It'll tell you the key is already in use/invalid and give you an option
    to enter another. Enter the original one you've got. It'll now activate
    OK.

    I'm definately putting it in properly. It's from a COA that I sold, and the
    other guy couldn't get it to work, so he sent a scan of the COA and I've
    also tried, making sure that I enter each character correctly.

    Is there any way I can tell from the COA if it's an RTM (or SP0) key?

    Yes - it won't work with SP1 or SP2 slipstreamed in.

    I've not found any other way.

    I'm sure there's one, but Microsoft has stayed totally silent on any
    way to tell besides an attempted install.

    So, now I have RTM images for the few machines that come in with RTM
    COAs and no / scratched CDs.

    Yes, it will. Since the slipstreaming won't change the code
    algorithm, to avoid the "Can't Reinstall" problem.

    Too much work to keep all of those images on hand, though B)
