[SOLVED] Duplicate user accounts after upgrading to Windows 10

Nat said:
Tried turning off password, rebooting, then turning it back on to no avail. If it's any help, I noticed that after logging onto the account with the square icon, the icon and text would change to that of the account with the circle icon.

There is definitely one user account on the system then, I'll need to find out where Windows queries when deciding which user accounts to show at boot.
 
you should find the information in the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\IdentityStore\LogonCache

Drill down to Sid2Name and you should find the accounts that show up when logging in listed there.
 
Hi,

Please execute the following commands from the Command Prompt to collect information from the system.

Code: 
reg query "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\Credential Providers" /s >"%userprofile%\Desktop\auth.txt"

Code: 
reg query HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI /v LastLoggedOnProvider >>"%userprofile%\Desktop\auth.txt"


The result of both command will be placed on a file named auth.txt that will be created on the Desktop, please attach the file to your reply.
 
Converting SID to name using command prompt, the first entry returns with the account name but the second entry returns with "No Instance(s) Available."
I've attached the result of the reg queries below.

Hi,

First make sure you create a System Restore point https://support.microsoft.com/en-us/help/4027538/windows-create-a-system-restore-point

Next open the Command as Administrator (Tutorial)
Execute the following command on the Command Prompt using Copy & Paste:
Code: 
reg add "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\Credential Providers\{538C240D-3DEE-4032-AB4C-08A3A6EB0861}" /v Disabled /t REG_DWORD /d 0x1
Restart the computer.

Please report the result.
 
It worked! Thank you for the help!

I was wondering, what may have caused it in the first place? And what did the code do? There are still the same two entries in the IdentityStore\Cache registry so did the code only disable the duplicate account?
 
Hi,

I'm glad it worked ;)

Actually it was x BlueRobot that posted the Tip on the private topic about this problem I just follow the directions and provided the fix for you...

Based on my research its seems that your problem is most likely related with Cyberlink Youcam, the software was probably registered as "Credential Provider", the way the registration is done and if enabled/disabled may not be transferred correctly by the Windows 10 upgrade and that resulted on the duplicated entries.

The registry change we did simply told Windows to ignore that Credential Provider.

Thanks. This seems to be working for me. I also had duplicate accounts issues after performing an upgrade to windows 10.
 
I have read all of the conversation on this topic, and I have tried the solutions suggested to no avail. My duplicate user name appeared on the login screen after updating to Win 10 Version 1909. One thing I tried out of curiosity was to create a new user and password. When I did this, the login screen showed the new user name twice as well. I have since removed that user name, and the two new names were both removed. Any suggestions you might offer would be appreciated.
 
Thanks for this solution!
I was able to resolve the same issue on my machine after Upgrading to windows 10 from windows 7!

Thanks this solution worked me also
 
Go to your Outlook or Microsoft account and change the password. Then restart your computer and when it gets to the duplicate name enter the new password. Windows gets stuck on stupid even tho you disabled needing to log in it still needs the login info. I did it and it worked for me
 
Disabling a "Credential Providers" entry removes the duplicate user account!

Thanks for this thread with the solution description.
