I just received a new PC with Windows 10 installed. When I first turned it on, it made me create a password. After it was setup, I went to Settings and sign-on options to remove the password requirement. It was working for a couple of hours, but when I started installing other software, somewhere along the way, when I restart the computer, it first displays "The Username or Password is incorrect. Try Again". That pops up even before I do anything. Then it shows two user accounts on the bottom left-hand corner, both with the exact same name. I have to switch to the top one and enter the original windows password and then I can get in. But when I go to Settings and Accounts, it only shows one account. I'm not sure why there is more than one account and what is happening on a restart.
