While installing Windows Vista / 7 / 8 / 8.1 / Win 10, you may noticed that at the end of the installation or setup, Windows prompts you to create a user account. Although, it is Administrator of that Windows PC, but Windows generates another super user or elevated Administrator during the installation, but that account remains hidden by default due to security reasons.
