If you computer originally came with Windows 10 installed, then the product key is embedded in the BIOS, and does not have to be entered when re-installing Windows 10.
During the installation of Windows 10, when you get to the screen where it asks for the product key, select the I don't have a product key link in the lower right corner of the screen, and the installation will proceed. Windows 10 will activate automatically upon completion.
Create Windows 10 installation media
