Download WOLF from my site:

Run the program.

Easy peasy.

Quick trick, the key is stored in memory under the ACPI/MSDM Tables.

Now reading it is the hard part, eventually WOLF will do this for you no questions, but until it does, it requires a memory reading utility.

For this, I used RWEverything Utility.

The author has made a very nifty program.

Instructions are simply, when the program loads for your OS version (32/64-bit), you click the ACPI shortcut up top.

Then choose MSDM. If your key is available, it’s in a simple string.

Note: You can still be unlucky in the fact that Windows 8 uses more letters in its product keys than Windows 7. IF you are downgrading and get the invalid character message, you have to contact MS to get it activated.

  1. guys good work on the program and it is something I need. I sent a friend request on FB asking if this will work on a usb boot drive with no os installed as I would need to pull the key from the bios in the process of repairing the motherboards.

  2. It currently only works on a windows environment. I maybe able to create a WinPE option, where it may work in a Windows PE environment (which can be bootable by USB drive.)

    At this time I have no plans to push that.

    You can always just install Win8/7 via an ISO and run this program while in Trial so you can activate after the fact.
