    I'm running WIN2K Server and see a key called ProductId rather than
    ProductKey in both HKLM\Software\Microsoft\Windows\CurrentVersion and
    HKLM\Software\Microsoft\Windows NT\CurrentVersion, and the number there
    isn't the CDKEY, it's the registration number that pops up in a little
    window during installation just after you enter a CDKEY, name and business -
    It's the one you're supposed to write down incase you need support.
    
    I don't think that you can find the CDKEY in the registry for WIN2K. Your
    advice for 95 and 98 is right though - haven't touched ME so I can't confirm
    your advice there.
