Hello
Thank you for posting in our Q&A forum.
To use a Group Policy Object (GPO) to disable the "Other Users" option in the Windows logon screen when the PC is joined to Active Directory, you can follow these steps:
- Open the Group Policy Management Console.
- Create a new Group Policy Object or select an existing Group Policy Object to edit.
- Right-click the selected GPO and select Edit to open the Group Policy Management Editor.
- Navigate to the following location in the editor: Computer Configuration > Policies > Windows Settings > Security Settings > Local Policies > Security Options.
- Find the policy setting called "Interactive logon: Do not display last user name" and double-click it.
- Select the Enabled option to prevent the last logged in user name from being displayed on the login screen.
- Click Apply, then OK to save your changes.
By enabling the "Interactive logon: Do not display last user name" policy, the "Other users" option on the Windows logon screen is disabled. This policy ensures that only the last logged-in user's username is displayed, preventing other users from entering their credentials directly on the login screen.
