Windows 10: Default User Name in HKLM-Winlogon & change in MSaccount log in

While inspecting the HKLM\Software\Microsoft\WindowsNT\Current Version\winlogon I noticed the Default User Name still holds a previous record of previous ISP email address existing previous to Jan 2015.
I did go into the Microsoft account and change the default email for the Win10 Microsoft Acct when I changed servers.
Obviously, there hasn't been an issue with this inaccurate registry default user entry but I wondered if it should be changed in the registry.

The reason I went to that registry entry was due to the Pin log in routine.
Yesterday the pin log in was not acceptable and I had to use the original password. The Anniversary update kb3189866 has been installed for a few days so it isn't a direct result.
I thought it might be connected to the fact I was trying to get a share working from the laptop(Home,MS account) to the Desktop (Pro, local account, no log in).It was an unsuccessful effort.
This morning the laptop log in was a choice structure -use password or use pin-2 icons. Previously I just started typing the Pin into the log in bar.
Is this the log in routine now?

How to change local account name?

Jayson,

This sounds like you are logged in to an MSAccount not a local user account.

The user account name for an MSAccount is set in your online MSAccount and cannot be altered on the computer.

User accounts log off immediately

Hi Sam,

I found this solution that you may want to try. It's a registry edit so make sure you back up your registry files before preforming

I found the solution
here

You may not be able to log on to system using either Normal Mode or Safe Mode. This occur only when Winlogon service tries to load the Windows default shell (explorer.exe) and user shell (userinit.exe) from registry. This service searches for Explorer.exe and
Userinit.exe in the following path of registry:



HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon

Edit these values and type the correct path of shell :



Shell = explorer.exe

Userinit=X:\windows\system32\userinit.exe



NOTE: These files may also be deleted by spywares. You may need to extract them using Windows CD.



Steps for rectifying this problem:

• Log on to a networked computer.
• Run Regedit.exe
• Point your cursor to HKEY_LOCAL_MACHINE
• Select File > Connect Remote Registry
• Type computer name (infected computer)
• Navigate to the following location in registry of destination or infected computer

HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon

• Edit these two values in right pane:

Shell

Userinit

• Change these two values to

Shell=explorer.exe

Userinit = x:\windows\system32\userinit.exe

• Exit from Registry
• Restart Infected computer.
• You should be able to log on to computer.

 

Just a followup to the two icons for a choice of log in with password or with pin.
Yesterday I assumed it was a change of log in format after the recent update. I clicked on the pin icon and logged in.
Today the login screen was back to the usual empty box waiting for the pin- no extra icons displayed for the choices.
Who knows what was happening but it has resolved itself somehow.
