I haven't found an easier key finder to use. As soon as Product Key Finder opens, all product keys and serial numbers that the program can find are displayed — no scanning required. It doesn't get easier than that. While both a pro and a con, there are only a few buttons in Product Key Finder — a Load Hive, Save, and Quit button — no complicated options to confuse you. I think Product Key Finder is, overall, a decent key finder tool. It's certainly easy and it found several serial numbers that some more common tools have never found.
