I have had no choice but to refresh my Windows 10 O.S. One result of this has been the spontaneous creation of a second account beside the original Administrator account. I would really like to remove the second account and in addition remove the need for a password when booting my PC to the Administrator account. As my home machine is used only by me with no one else coming near it, the demand for a password is just an irritant that slows me down. How may I achieve these two changes ?
