What is the purpose of "Other User" on the login screen (Domain Env)

Laptops on Windows 10 Pro seems to show this useless "Other User" option which is defaulted. This requires people to click "Local or domain account password" in the lower left in order to be presented with fields for their username and password. Is there a way to eliminate "Other User" or at least have the system present username and password fields under this option? My desktop on Windows 10 Pro seems to show username and password fields under the "Other User" text, much like it does in this how to: Sign in Screen - Do Not Display User Name in Windows 10 - Windows 10 Forums Not sure what makes a laptop different or how I can make the behavior match.

The only special options we have configured via Group Policies are these:
Default Domain GPO elements regarding login:
Computer > Windows > Security > Security Options > Local Policies
Interactive Logon: Do not display last user name - Enabled
Interactive Logon: Message text for users attempting to log on - Defined with our AUP/Disclaimer
Interactive Logon: Message title for users attempting to log on - Defined with our company name.
Computer > Administrative Templates > System > Logon
Assign a default domain for logon - Enabled and defined with our domain name
Always wait for the network and computer startup and logon - Enabled
Hide entry points for Fast User Switching - Enabled (via local policy because I am testing if this makes a difference or not).
I noticed I need to have "Hide entry points for fast user switching" enabled in Windows 10 so on a reboot it does not show the last user name when trying to log in.

This is not exclusively a Windows 10 issue. It used to happen in earlier versions as well.
Check here: Group Policy \Computer Configuration\Administrative Templates\System\Logon\Exclude credential providers
Disable the MS account credential provider (you need to check which entry it is).

What other versions of windows exhibited this problem? My laptop is running 8.1 and has no issue logging into the domain.

I forgot to mention in GPO from Default Domain Policy we also have this enabled:
Computer > Windows > Security > Local Policies > Security Options > Accounts: Block Microsoft Accounts - Users can't add or log on with Microsoft Accounts.

Not sure how check which entry MS account credential provider is. I thought it would be a CLSID but googling it no one seems to publish what that CLSID is.

Microsoft account is: F8A0B131-5F68-486C-8040-7E8FC3C85BB6

Ok I broke the laptop login. I tried to make the credential providers match what's on my Windows 10 desktop. So I noticed the laptop has two credentials in the registry location that my desktop does not have. They are both Onex credential provider and onex smartcard provider. I put both of them in the exclude credential providers local group policy to test, the values are: {07AA0886-CC8D-4e19-A410-1C75AF686E62},{33c86cd6-705f-4ba1-9adb-67070b837775}. Rebooted and now it just says Other User on the screen with no fields to enter any information! There is nothing in the lower left corner or anything. Literally its a giant paper weight.

So I fired up mmc as a domain admin from another machine and added the local group policy snap in for the laptop machine and luckilly I can undo that setting and reboot the laptop.

I did notice that Assign a default credential provider is populated with this value: {60b78e88-ead8-445c-9cfd-0b87f74ea6cd}
According to the registry that is PasswordProvider. This was me trying to get a password prompt as the default a few weeks ago without success, so I think I'll undo that while I'm here as well.

Thanks Kanta. I thought that may be it since in the registry it says WLIDCredentialProvider (WL as in Windows Live ID ?).

I was able to fix my mess up via the local group policy snap in and remotely running gpupdate /force via psexec, so now I'm back to square one. I put in the windows live ID credential provider in the Exclude credential providers, ran a gpupdate / force and rebooted the machine. Didn't make any difference. Still shows "Other User" as default with no text boxes to do anything. Have to click on Local or domain account password in the lower left. I found this how to here: How to assign default Credential Provider in Windows 10 And I tried that with PasswordPolicy credential provider GUID but unlike what that article says, nothing appears as "default" on the Other User tab.

I'm at a loss as to how this is programmed.

I have a Sony Vaio SE2 that I had to undo Windows 10 on it because after upgrading 8.1 to 10 All I got was the "Other User" screen with nothing to click on, so it was impossible to give the system login credentials. For the record this computer, (and all computers) with this topics behavior are Dell Latitude E5440's.

If it's fairly certain that it's mostly on these Dells, perhaps a call to their support may be worthwhile. If you get the right person you may be in luck.

Hi kjstech! Try to disable this group policy "Interactive Logon: Do not display last user name". Reboot your computer and the next time Windows login screen will display your last user name as the default login instead of "Other user".

Hmm I would but that is our Default domain policy. Then we can't join the domain.

I could break it out into its own GPO and use GPO Filtering to not apply it to Windows 10 machines, but its mandated company security policy.

Ok that just makes things even weirder.
Reboot the machine, get 4 icons down the left.
The first icon is the last user logged on (Me in this case), but NO password field so its useless.

The second icon is Other user, again no password field so another useless tile.

Third is password, but the user is pre-populated and unchangeable previous user name but with an editable password field.

Fourth is local or domain account password which provides a user name and password field (what we want to default to).

Fifth is Smart card which does nothing. There were two of these but when I disabled both Broadcom smartcard devices in devmgmt.msc, it brought this down to one of these.
