I have a couple family members with busted computers. Windows 10's "reset this PC" from recovery environment was a no go. I pulled out a windows 10 USB i made many moons ago with the media creation tool and reinstalled windows 10 using it. I then used nirsoft's Produkey to recover the product key because I knew the manufacturer has it embedded on the machine itself.
It retrieved this key for me, but to my surprise it also returned another key which is the key for my copy of Windows 10!!! This is not okay with me, I do not want my key floating around in the world.
How can I make a clean installer for Windows 10 that doesn't carry my product key embedded in itself?
