XP product key is not valid.

I have an old HP Pavillion with XP dv8000. It became too slow to use over the years, so I deleted the operating system, which re-formatted disk and tried to reinstall XP using 3 separate disks in Win XP (legitimate) I. Windows refuses to install, saying that the product key is not valid. I used the key on all 3 of the discs, as well as the original key on the bottom of the laptop. Am I out of luck? Thank you.

What type of drive you are using to install XP?

You can use the recovery disk that came with the PC (or created from the original installation), or OEM System Builder drive with the key on the case. Disk and the key must also be to the same edition of XP (Home or Pro)

If you have a disk with SP3, you can install by using the default key, and then change the key of the COA, one using the tool to update the key product - http://www.microsoft.com/genuine/selfhelp/xppkuinst.aspx

    I raise reading Microsoft license Validation could be responsible for such messages.
    This tool distributed by Microsoft through its Windows Update platform for some time considered the factory image Toshiba installed an illegal copy of Windows XP.

    I think that to avoid popping up this message, you must remove this License validation tool.

  • My windows product key is not valid.

    Hello

    My windows product key is not valid. It shows that I don't ' have a genuine windows, and so I entered the product key to activate

    and its not to validate. It was workiing before, just do not know what happened.

    Help, please.

    Thank you!

    I wanted to tell the name of version (e.g. Windows 7 Home Premium) printed on the sticker.  Is the version currently installed on the PC of the same version?  Check in Control Panel > system page.  The number is the ID of the product that is not supposed to be the same as the key.

    If the versions are identical, then the problem is a bad character entered, almost always.

    If the product key is readable, then you can certainly use it to Clean install Windows Upgrade 10. Look over the steps and ask in return if you have any questions.
