Local account still requires password

I set up my pc using a local account not a Microsoft account. I then ran netplwiz and unticked "users must enter a user name and password to use this computer". This having been done, it generally boots up without the need for a password; however, on a regular basis it will bring up the password screen when starting the computer for the first time. If I click on restart (as opposed to entering a password) it invariably boots up the second time without asking for a password. I should add that it never happens when coming out of sleep.

This is more irritating than problematical but I wonder if anyone has any idea why it should happen?

Thanks for any thoughts.

Thanks FreeBooter - I'll look at this and see if it helps.

You are very welcome!

Maybe you have Password Expiration set to 'Enabled'?
Password Expiration is a feature in Windows that forces a local account on the PC to change their passwords when a specified maximum (42 days by default) and minimum ( 0 days by default) password age has been reached.
It can be disabled via elevated command prompt. The picture is from an article by 'Brink' on this forum but I think it was a long time ago.

As per OP, I have run netplwiz and done the necessary there and my password is set to never expire. Call me timid but I am reluctant to change things in the registry. The duplicate local account seems a wise precaution thank you, but otherwise I think I have to accept this is one of those W10 aberrations and that it will keep happening. Thanks for the various ideas.

Thanks Try3 for clarifying source of my input.
