3 Keyfinder Commercial Product Program

In addition to many free keyfinder programs, some commercial keyfinders are also available to help find your serial number or lost product key.
The product key or serial number of the program is usually placed with the original DVD or CD. If you lost this license key, you can usually find it in the registry but it's not easy. This is what a viewfinder program does for you, automatically.
Important: Please read the Frequently Asked Questions about my Keyfinder Program before you pay for any viewfinder programs.
Here are the top 3 commercial key search programs

Jalapeno Keyfinder is a simple, easy-to-use viewfinder program.

I tested the Product Key Explorer using their demo version, limiting the product key recovery to the first 4 characters.
3 Product Key Finder
Product Key Finder is another commercial viewfinder tool that you can find in your searches.
