Hey all, I used one of my Windows 7 licensees for a computer that I gave to my sister. The computer died, I think it's the power supply or motherboard. The system is so old (single core Intel 3.4ghz CPU), that it's going to the dump, no other way to deal with it. She got a new computer with Windows 10, so she does not care about it. I want to get my license back off the computer, it's a Retail license so it can be moved system to system if needed. All I have is the hard drive with the Windows files on it. Is there a file that I can pull off the HD so I can capture the KEY I used on the system ? It's one of 3 but, not sure what one it is... Plz help !
