AutoAdminLogon in Windows 10 reset to 0 after reboot

Hello,

We enable the Auto Logon feature in the registry in Windows 10. Everything works fine for a while then all of sudden the computer would ask for password entry after reboot.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"EnableFirstLogonAnimation"=dword:00000001
"AutoAdminLogon"="1"
"DefaultUserName"="LocalAdminUser"
"DefaultPassword"="localAdminPWD"

The AutoAdminLogon reset to 0 and the DefaultPassword is missing in the registry. Is there any registry setting we need to include?

Thanks,
Brian.

    Hi Brian,

    It seems the DefaultPassword is not required for the Autologon, also I would enable the logging for this type of issue to troubleshoot the issue.

    Hello there,

    Open regedit.exe and browse to HKLM:\Software\Microsoft\Windows NT\Current Version\Winlogon which is where you will also be storing the autologon username / password / domain, you should check for a DWORD called AutoLogonCount.If this is set to 0, then on next reboot it will strip the password and set the AutoAdminLogon value back to 0. If you up the number, or simply delete the DWORD, all should come back to life as you'd expect.

    The below thread discusses the same issue and you can try out some troubleshooting steps from this and see if that helps you to sort the Issue. https://social.technet.microsoft.com/Forums/windows/en-US/c103121f-6361-4918-b751-a8e835dab9a2/autoadminlogon-is-set-to-0-when-rebooting?forum=w8itproinstall

    I hope this information helps. If you have any questions please let me know and I will be glad to help you out.
