  1. I recently re-formatted my HD and reinstalled my original copy of WinXP SP3.
    However, I am unable to get my WindowsXp Product key to work.

    When I go to activate the 25 digit key, it keeps telling me that it is invalid.

    I do not have the original paper with the key on it. I had to use a key-finder program to get the key from the registry.

    Is Microsoft still activating Windows XP product keys? I only have 29 days to re-activate the product key and windows XP.

    Hey Scott,

    Do you know what version the Key is for (ex. Pro or Home)

    And do you know if this is a Retail or OEM key?

    Also, do you know what version you installed with?
