Forgot your Windows XP Product Key? How to recover your Windows XP Product Key?

If you do not remember your current windows XP product key, look for a file called “Unattend.txt“. You will find it either on your Windows XP Disk or in your Hard-disk drive.
This file will contain the product key for your current Windows XP installation.

Tool to Find key for Windows OS 

  1. If your system came pre-installed with XP, the Product Key that any (free or paid for) key finder or system resources utility retrieves most likely will be the Generic Key the OEM uses to install and NOT the Product Key you need to reinstall.
  2. If you successfully reinstalled XP since the initial OEM setup(i.e. The first time you booted the computer), the Product Key if requested and input from the key located on the case or generic OEM sticker label will be the valid Product Key supplied with the computer.
  3. If XP was not reinstalled the retrieved Product Key will be the generic Product Key used by the OEM and will return an invalid message when used to reinstall from the OEM disk. The correct Product Key will be the one from the sticker on the outside of the case.
  4. The Product key is not hard coded [i.e. does not have a singular unique identity] to the Windows XP CD or any other version of Windows installation disk media.
