This upgrade to Windows 10 has been anything but smooth for me. I am ready to pull my hair out! Ever since doing the upgrade, whenever my computer starts up, the first screen has my name (and email address) and an Administrator listed in the bottom left hand corner. Why 'Administrator?!' I am the Administrator! Tonight I tried to disable the need for a password every time I start my computer, and I did the latest update. Guess what?! I now have my name (and email address) and TWO Administrator accounts listed on the start-up screen! What's going on? How can I set things to where I am the only User/Administrator on this computer, and no login password is required?
