Windows Key Finder is an Open Source app that uses the Command-Line to retrieve your Windows product key.

Windows Key Finder is a portable executable that will try to retrieve your key from the Command Prompt once executed. Double-click on the EXE and your product key should be displayed. It's simple and only takes a few seconds.

Our experience is that retrieving your Windows key can be hit or miss based on your type of Windows. For example, you might have an OEM, Retail, or Volume product key. Each key is stored differently. If the program does not work, check out the Similar links below.
