Help! I've lost my Windows 7 product key

What to do when you can't find your Windows 7 product key

What to do when you need the product key for your PC's Microsoft Windows 7 installation, and you don't know where to find it.

QUESTION I'm helping a friend who has lost his Windows 7 product key. I understand there's a utility that can access this information in the Registry. Can you help? M Higgins

HELPROOM ANSWER There are many utilities that can retrieve your Windows 7 product key. We've had success using the free Magical Jelly Bean Keyfinder, which is simple to install and run. Launch the program and the key will be displayed.

Ignore the features list, which suggests that you must pay for the Premium version to retrieve your Windows 7 key.
