I am buying a new Solid state drive for my computer running windows 10. But before I do I wanted to know do I need to know my product key. The computer was running windows 7 ultimate before I upgraded to 10, when I upgraded the first time I was glad to see I didn't need the key and everything was handled by the media creation tool/updater. But after looking around I cant find a definite answer as to if i need to know the product key when doing a clean install onto a new SSD.
