MDT - Start session after final reboot with renamed default admin account

Question

Hi everyone,

i'm trying to start windows with renamed admin default account after MDT deployment finishes without writing down the new account.

I mean,

1.- As very last step before last reboot, i run a command line to rename the default administrator account mdt uses with wmic

2.- when the system reboots the account displayed in username textbox is the default account name ADMINISTRATOR instead of mine, renamed one.

I have to delete administrator and write down the "new" account name, for example, SysAdmin.

is there a way to start displaying SysAdmin in username textbox? so i dont have to delete and write every time i deploy a machine?

thks in advance,

Hello

Yes, you can achieve this by updating the MDT AutoLogin registry settings after renaming the local admin account. Here is a script that does exactly that:

'//—————————————————————————-
'// Global constant and variable declarations
'//—————————————————————————-
Option Explicit
Dim iRetVal
'//—————————————————————————-
'// Main routine
'//—————————————————————————-
'On Error Resume Next
iRetVal = ZTIProcess
ProcessResults iRetVal
'On Error Goto 0
'//—————————————————————————
'// Function: ZTIProcess ()
'//—————————————————————————-
Function ZTIProcess ()
    Dim colUserAccounts
    Dim objUser
    Dim oAccount
    Dim AdminAccount
    Dim strComputer
    Dim objNet
    Set objNet = Createobject ("WScript.Network")
    strComputer = UCASE (objNet.ComputerName)
    'Determine Local Administrator Account
    Set colUserAccounts = objWMI.ExecQuery ("Select * From Win32_UserAccount where LocalAccount = TRUE")
    For each oAccount in colUserAccounts
        If Left (oAccount.SID, 6) = "S-1-5-" and Right (oAccount.SID, 4) = "-500" Then
            oLogging.CreateEntry "Renaming regional Administrator account to Admin" , LogTypeInfo
            AdminAccount=oAccount.Name
            oAccount.Rename "Admin"
            oLogging.CreateEntry "Updating MDT autoLogon key with renamed Administrator info (Admin)" , LogTypeInfo
            oShell.RegWrite "HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon\\DefaultUserName" , "Admin" , "REG_SZ"
        End If
    Next
    iRetVal = Success
    ZTIProcess = iRetval
End Function

This script renames the local admin account (in any language) and updates the MDT AutoLogin registry settings. You need to replace "Admin" with your desired username on the two lines shown below:

oAccount.Rename "Admin"
oShell.RegWrite "HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon\\DefaultUserName" , "Admin" , "REG_SZ"

After running this script, the system should display your renamed account in the username textbox after reboot.
