Assuming the laptop came pre-installed, the Key is on the COA sticker on the case (or inside the battery compartment)

Hi thx1139,

I don't know how to do it in Jelly Bean, but I do with ProduKey:

Your Windows 7 product key is stored in the software registry hive, located here:

C:\Windows\system32\config\software

Please note, software is the file name, not a directory. It has no file extension. Your drive may have a different letter.

This is a little program that will tell you the product keys of the various software installed on your computer. What makes this different, is the ability to load keys from an external registry hive. Exactly what we want
smile.gif.pagespeed.ce.8xZGdnoS_z.gif


So if you download and run ProduKey (by NirSoft):

http://www.nirsoft.n...key_viewer.html

Then press File > Select Source, you will be presented with a new menu. On this, select Load the product keys from an external Software Registry hive and you will be prompted to open a file. Navigate to the software hive on the external drive and open the hive. E.g. D:\Windows\system32\config\software. You should now have your product keys

Hope this helped.

Thanks a lot, Tom! I'd never have managed that without you and you saved me a lot of hassle (and maybe tears!) :)

I see the "software" and the massive size it is

[05/25/2013 08:17 AM 72,876,032 software]

But I might be running the "app" incorrectly, cause it does not read the key, just says "unknown' on the product key.
But I am pointing it to the correct location which is

C:\Windows.old\windows\system32\config\
