Perhaps the path is more general:
1) KERNEL32.ExitWindows*() calls ADVAPI32.InitiateSystemShutdown*();
2)  ADVAPI32.InitiateSystemShutdown*() issues a "InitiateSystemShutdown" 
request to the SM (SMSS API # 1);
3) the SM propagates the shutdown request to every environment subsystem 
it started since bootstrap time (still active ones, of course);
4) each environment subsystem, on shutdown request, releases every 
resource it aquired during its life (processes, memory etc); the dies;
5) when every environment subsystem has gone to bed, the SM actually 
initiates to shutdown the kernel and executive.
