Scripting

You can push a registry key to change to enable autologin and restart the machine

reg.exe add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinLogon" /v AutoAdminLogon /d 1  /f

reg.exe add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinLogon" /v AutoLogonCount /t REG_DWORD /d 2  /f

reg.exe add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinLogon" /v DefaultDomainName /d tmccacad  /f

reg.exe add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinLogon" /v DefaultUserName /d user  /f

reg.exe add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinLogon" /v DefaultPassWord /d xxxxxxxx  /f

shutdown -r -f -t 10

What is your end goal with a logon script?  Are you trying to run a script or MI without someone logged on?

If so, you can do that in both since they run using LocalSystem.  You can run as other users in a script as well as logged on user.
