I got a Dell Vostro Notebook in Oct. '21 and a Dell Vostro Desktop in Apr. '22, both came with Win10 Pro and during setup I did not have to enter any Product Key like had to be done with Win7 and earlier. It was a change in the process beginning with Win8. That should remain the same for any install/reinstall/repair of Win10 and no additional cost. Changing from the Home edition to the Pro edition will have a cost for a new license.
