I threw out a Windows XP machine a while ago (the motherboard failed). I kept the hard drive and the XP installation media.

Problem is the license key was on a sticker on the machine - doh! The original manufacturer has gone bust (Evesham) and I suspect that Microsoft will be of little help.

Is there any easy way to get the license key off the hard disk? Can I just find the file with the registry data in it and get the key using a hex editor?

I really need a spare XP key for use in a Windows VM.

If the old machine had a sticker, it was most likely an OEM license.

OEM licenses cannot legally be moved from one computer to another one. They die when the computer dies.

But, in answer to your question..

Load the old registry hive on your new computer and then find the XP key. -- EDIT make sure that you open the SOFTWARE hive instead of SYSTEM mentioned in the first guide, then open this just-opened-offline hive in the second guide.

and while you're at it, backup your XP activation files, AFAIK the latest WinKeyFinder features this option, if not, here'a a tutorial.

Apparently Nirsoft's ProduKey can do this:

produkey.exe /windir [Windows Directory]

Load product key information from another operating system on the same computer. The [Windows Directory] specifies the base folder of Windows installation, for example: c:windows, c:winnt This feature is only supported on Windows 2000/XP/2003/2008/Vista/7. Avast driver update serial.

If that doesn't work, you'll have to dig it out of the registry file manually by searching for the registry key

using a hex editor I think.

Bytes 52-66 (0x34 - 0x42) of this key hold a 15 byte number.

In Hex, it's a 30 digit number:A2 23 51 D0 2A 38 5D 22 C4 41 6B 87 43 C1 00

In Binary, a 120 digit number:10100010 00100011 .. 11000001 00000000

I did it this way about 4 years ago, so I'm really hoping ProduKey works.

This article might be useful: Find the Windows XP Product Key Code.
There is also this another link on a ViewKeyXP tool: Retrieve your XP Product Key.
(that second link has some other tool references too).
