What should I do if Win10 cancels the power-on password and then starts two accounts?

What should I do if I turn on two accounts after Win10 cancels the power-on password? Why are there two users in the win10 system? The original computer has a password, and then win+r enters netplwiz to cancel the power-on password. This problem just happened yesterday, and it is the password login error. What should I do?

1, press win+r to open the run, enter netplwiz to open the setup menu.

2. Select the account with the password-free login, check the password for using the computer, and click Properties to open the property menu.

3, complete the user name.

4. If you need to use the computer, you need to uncheck the password option, and you can confirm it.
