Windows 8.1 Group Policy to Force Domain Logon as Default?

Question

I recently purchased a new Windows 8.1 computer for use in our organization.  The default logon option for the device is for a Microsoft Account (the default username field prompt is for an e-mail address, rather than for a username.)  However,
I would prefer that the default logon option be for a Windows domain account logon, so that users don't have to click the "Sign-in options" link and select "Local or domain account password" each time they need to log onto the computer.
I have learned that setting the "Interactive logon:  Do not display last user name"
policy (located under Computer Configuration / Policies / Windows Settings / Security Settings / Local Policies / Security Options) to
Disabled allows the domain logon option to be retained across sessions.  However, I would prefer to keep this option set to Enabled so that the previous user name is not displayed.
Does anyone have any suggestions on how the default logon option can be forced to a domain logon, while still suppressing the display of the last username?

Hi Arowitv,
According to your description, we can use the following policy to check the result.
Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options:
Accounts: Block Microsoft accounts
Click this option, and select" Users can't add or log on with Microsoft account"
Note: Selecting this option might make it impossible for an existing administrator on this computer to log on and manage the system.
Computer Configuration\Administrative Templates\System\Logon :Assign default domain for logon
Set the option to Enabled, and add the Default Logon domain.
Hope this helps.
