Solved "Other users" present in lock screen of W11 enterprise but no idea who's account

mystvearn · Jan 9, 2024

I found this when I locked my windows, but no idea who it is. Not available under my accounts. I tried to see who it is by clicking, asked to put login details. How do I I delete this account?

Sometimes a clean Windows install will experience errors during the Out of Box Experience (OOBE), and fail to remove the temporary user defaultuser0. This remnant shows up as "Other user" on the logon screen.

It's most harmless, you can't logon on this account.

Open Regedit and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

Right click on the ProfileList key and select Export before you make any changes. If things do not go to plan, you can restore the key using your exported .reg file.

Look for a Default0 user. If it is present then delete it.

The ProfileList key should look like this:

Note:
The S-1-5-18 is the system profile.
The S-1-5-19 is the Local Service profile.
The S-1-5-20 is the Network Service profile.
The S-1-5-21-3509888341-461846594-3914475199-1001 key should be your user name profile. Enter the key and check the ProfileImagePath to be sure.
The S-1-5-21-3509888341-461846594-3914475199-500 key is for the Administrator account, which I have enabled. It should not be present if you have NOT enabled the Administrator account.

I found the folders as mentioned. The long one is my own user account. What do you mean by enable? How to know what is/what is not enabled? When I right click and modify the ProfileImagePath, I see my username. What should I do next since the "Other users" is still there.

I do not see the "other users" there. Previously, I got this error in login details.

I checked the certificates, I found this

While the SSO_POP_Username is my personal email address, the username shown is not any of my known usernames. After removing the certificates, I no longer get the windows login reminder.

In order to use the Administrator account, you must open a Power Shell window and enter a command to enable it.
Get-LocalUser -Name “Administrator” | Enable-LocalUser

To disable the Administrator account, enter:
Get-LocalUser -Name “Administrator” | Disable-LocalUser

I would run a malware/virus scan on your machine, just to be on the safe side, especially if you did not add that certificate etc...

When I run the code, I get:

Enable-LocalUser : Access denied.
At line:1 char:40
+  Get-LocalUser -Name “Administrator” | Enable-LocalUser

    + CategoryInfo          : PermissionDenied: (Administrator:LocalUser) [Enable-LocalUser], AccessDeniedException
    + FullyQualifiedErrorId : AccessDenied,Microsoft.PowerShell.Commands.EnableLocalUserCommand

My IT department also told me to run that. I did follow these steps until removing the certificates.

Did you open Power Shell 'As Administrator' ?

I probably should have mentioned that earlier

That certificate was more than likely added by Microsoft, but I hate it when they use user names like that. They can so easily be malicious.

At least you can have some peace of mind knowing that it's not malicious now.

Is this a work computer, or did they just give you some friendly helpful advice (sounds like a good IT department

Yes, IINM. The security division troubleshooting via virtual machines and deleted my personal account account from the login details. Hopefully it will settle the problem.
