You can use any of the commented constants to perform the explained function. You might need to adjust the process privilege on NT based OSes.

if not ExitWindows(EW_RestartWindows, 0) then ShowMessage('An application refused to terminate');

{
Value	Meaning
EWX_FORCE	Forces processes to terminate. When this flag is set, Windows does not send the messages WM_QUERYENDSESSION and WM_ENDSESSION to the applications currently running in the system. This can cause the applications to lose data. Therefore, you should only use this flag in an emergency.
EWX_LOGOFF	Shuts down all processes running in the security context of the process that called the ExitWindowsEx function. Then it logs the user off.
EWX_POWEROFF	Shuts down the system and turns off the power. The system must support the power-off feature.Windows NT: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Remarks section. Windows 95: Security privileges are not supported or required.
EWX_REBOOT	Shuts down the system and then restarts the system. Windows NT: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Remarks section. Windows 95: Security privileges are not supported or required.
EWX_SHUTDOWN	Shuts down the system to a point at which it is safe to turn off the power. All file buffers have been flushed to disk, and all running processes have stopped. Windows NT: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Remarks section. Windows 95: Security privileges are not supported or required.}
