Hello. This is Emily
Type netplwiz in the search on the taskbar and hit enter to launch Account. select your user, if the "user must enter a username and password to use this computer" box is NOT checked, please check it , click Apply. Then uncheck the box and click Apply. This will bring up a pop up window.
On this pop up window, very important, erase the username that's prefilled. Username should be your entire local user’s username. Password is your account's password. Any typo here can prevent it from working. Then click OK. And back to the netplwiz page, click OK.
Restart the computer now and see if it works without prompting you for password.
