"Recover product key from dead HDD...Hi, recently, my laptop had a motherboard issue that lead to the death of my PC. Almost every component is damaged, I brought the laptop to a PC repair shop but they couldn't do anything. We tried to recover at least the HDD, without success. I'm currently building a new PC and I wonder if there's a way to get back the windows license. Thanks in advance for the help." -- Microsoft.com
