Can you try this version I’ve just compiled, it might fix your problem:

Thanks for your post. ProductKeyFinder will recover keys from windows.old files no problem.

MAK Keys are not stored on the system, so it’s not possible to recover them.

Thanks

If I understand correctly you are looking for a way to decode a Product Key stored in the Windows registry hives, and that the key type you are looking to decode is a MAK Key?

I found this page by doing a Google search on the first portion of a key I decoded from an install.wim file from a Windows 7 installation disc.

The key I found slightly differs from the one I found on this website, and I was wondering if it was another MAK key. The program algorithm actually looks like it would be quite simple to the regular person but the math is actually very complex. I am actually wondering if it is because I am using a 64-bit machine that it is actually able to decode?

The key that I got was JVF76-6TMPY-98BXW-76B7Q-TCGTV.

The actual script that I wrote (with the help of an online resource and another programmer over the internet) is made with pure JavaScript and the actual contents can be trimmed to make the file very small. The source code is publicly posted on the internet and can still easily be found on google by doing a search for “javascript product key”. It should be at the top of the list on webdeveloper.com.

I successfully rewrote the program in C++ (learning the language as I went). Both the JavaScript and the C++ version compliment each other in the fact that the Javascript version extracts the current Product Key on the system and the C++ version can extract the key(s) stored in a registry hive from an offline system in a command prompt interface (useful in recovery and multi-booting scenarios).

Anyways, if you use the JavaScript version you can easily modify it to read from a different location of the registry. Couple it with a .cmd file and the reg.exe utility with the load/unload parameters and you can even view the registry of an offline registry hive.

I used Microsoft ImageX to mount the install.wim file off of the Windows 7 Installation disc to a folder on my harddrive (using the image identifier 2 for Home Basic). Then I copied the software registry hive file from windows\system32\config to my harddrive. I mounted it to the registry using the command-line “reg load” and told my .js file to point to a subkey of my loaded hive “HKLM\\TempHive\\Microsoft\\Windows NT\\CurrentVersion\\DigitalProductId4″. The key regular one appears to be a plain old “trial” key, kept around since the beta stage.

MAK keys cannot be recovered, as they’re not stored in the system.

Thanks

Can you contact me directly (see the Contact menu link) and I’ll provide you with some steps we can try

Thanks

I located Windows.old\Windows\System32\config\software using load hive but all that it returned was the Microsoft windows 7 professional key.

Thank you very very much!
