I kept the hard drive and the XP installation media.</p> <p>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.</p> <p>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?</p> <p>I really need a spare XP key for use in a Windows VM.</p> http://www.goboef.nl/?id=questions/32367/-/32369#32369 2 Answer by nik for Recovering a Windows XP License key nik http://www.goboef.nl/?id=users/263 2009-08-30T12:41:00Z 2009-08-30T12:41:00Z <p>This article might be useful: <a href="http://pcsupport.about.com/od/tipstricks/ht/findxpkey.htm" rel="nofollow noreferrer">Find the Windows XP Product Key Code</a>.<br> There is also this another link on a ViewKeyXP tool: <a href="http://michaelstevenstech.com/ViewKeyXP.htm" rel="nofollow noreferrer">Retrieve your XP Product Key</a>.<br> (that second link has some other tool references too).</p> http://www.goboef.nl/?id=questions/32367/-/32377#32377 5 Answer by Kez for Recovering a Windows XP License key Kez http://www.goboef.nl/?id=users/6937 2009-08-30T13:13:06Z 2009-08-30T13:22:36Z <p>If the old machine had a sticker, it was most likely an OEM license.</p> <p>OEM licenses cannot legally be moved from one computer to another one.
