Need To Extract XP Key To Restore

Posted on 2008-10-31
Last Modified: 2012-05-05

I currently have a computer that has two versions of Windows XP Home Edition on ONE partition.

The non-working version [C:\WINDOWS] does not start up at all.
The working version (fresh install) installed in [C:\WINXP2] is temporary as I want to restore the system completely.

Now, I am wanting to log on to the working version and get the Windows XP key from the non-working version, whether it be through the registry, command-line, script, etc.
The reason I am wanting to do this, is that the serial key that is located on the front of the computer (on a Microsoft sticker) has been ripped - therefore, missing the first four digits.

I have a really high doubt that Microsoft will supply you these first four digits, even if you prove you own the key... So I was wanting to rip the serial key out of the non-working version of Windows.

Much help will be appreciated.

Thanks, Brendon

Download and run BelArc -
You should see the key under "Software Licenses" in the profile of your machine.

here how to do it :
Try this key finder, it has command line options for retrieving keys from remote disks/folders: (as suggested)

in your case maybe:
produkey.exe /regfile "F:\WINDOWS\system32\config\software"

Thanks a lot guys.

Igor and Nobus, you both gave me the same link to the download I was looking for, but Nobus gets a little extra for explaining quickly how it is used.

Deepika, you lead me to a good download, but I am unable to use it as I can not access the registry (can't get in to Windows). But I gave you points for assisting anyway.

Whsum, thanks for the link - but unfortunately, I wasn't able to use it.
