XP: Find Your Windows Product ID / CD Key Code in the Registry

Need your Microsoft product id but can’t find your original documentation?


We often need to know the product id but most of us never keep up with the original packaging which contains this vital number.

–Prior to XP:

Now, don’t go changing this number…

Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

The number is listed under ProductId

Look but don’t touch.

–XP:

Thanks goes out to j.cox for pointing out the error (see comments below). We had forgotten about this “new feature.” Anyway, to get around this you can download and run the application required to view the XP install code found here:

    I am not able to access (forbidden) the Magical jelly bean to find my product key. My 2yr old ripped part of the sticker off of the top of my computer and now I can’t reinstall the sound device I removed by accident so their is no sound on my system now. Can someone help me find my product key?

      You probably don’t need your product key for this.
      You need instead the driver disk for your sound device.
      You can most likely download it from the computer manufacturer’s site if you have misplaced the cd.

      The Product ID an encrypted form of the 25 digit product key. Use Magic Jelly Bean Keyfinder to locate your installed product key

    You can also know the Windows XP product key by looking in System Properties-
    in run dialog box, type “sysdm.cpl” or press [Windows+Pause] button simultaneously.
    In General tab look for the 20-digits Product ID in “Registered to:”section
    in the format:
    xxxxx-xxx-xxxxxxx-xxxxx

    e.g. 55274-642-4643641-23082

    I was given a bunch of computer towers that were stripped out, and have the Product Key number stickers on the side.

    I just loaded a system with my personal copy of Windows XP Home Edition, but when I change the registry entries to the Product Key, I will also need to locate the matching Product ID.

    Is there any way to locate this data without the original load of the OS?

    The hard drive on my computer has broken and the product key has rubbed off so I can’t read it. Is there anyway I can find out what the product code is?
