Win10 doesn't always recognize my password

This happened back in July, then again last month. At boot up win10 does not recognize my sign in password for my local user account. Since I know my password I typed it in again, no good. I spent the rest of the day retrying my password. Must have typed it in 100 times, then for no apparent reason it recognized the password and I'm in (same thing in July). First thing I did was removed the need to login at boot up. To be honest I don't remember how I did it. I found some help article online and followed the instructions. I think I ran netplwz to do it, but I don't remember for sure (that was a whole month ago). Anyway I am finally getting around to fix the problem. I have not rebooted the computer since this occurred. Today I tried to set up a pin in settings, windows prompted for a password but did not recognize my password. Went to change the password, same thing. I know I removed the need to sign in, but it still requests a password. I found a tutorial here which pointed me to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
This shows no line for default password. Auto Admin Logon has a value of 1. Default Domain Name and Default User Name both have accurate values.
The question is will my computer boot without needing a password? Thanks for the help.

If the local user account causing the problem you can reset user account password with simple command.

In Windows 10 type cmd.exe into Start Menu, right-click on Cmd.exe, and open it as an administrator.

From Command Prompt execute below command to reset your user account password.

Code:

net user adl6009 *

Press Enter key twice to reset the password of user account named adl6009. If you don’t know what the Windows user accounts are, type command net user firstly to view all the user accounts. Please replace adl6009 with your user account name.

If the user account is Microsoft account then reset your Microsoft account password from below link.

How to reset your Microsoft account password

Thanks for the help. I will have time tomorrow to play with it. I will post the results, if it works :)

I followed you procedure and created a new password, maybe I made a mistake and used my old password, but the computer reboots and starts up. The weird thing is it does not request a password. I used the cmd prompt and entered the password, then confirmed it, I figured windows would then require it at start up. To continue with the weird behavior, I wanted to view my saved passwords in google chrome, before this chrome would require me to enter my windows password and windows would rejected it. Now windows accepts the password without a problem. In any case thanks again for the help.

You are very welcome!
