What if winlogon.exe is run by csrss.exe and not by smss.exe? A winlogon process, in its own desktop, is needed for each Win32 session. If we make csrss.exe multiuser, it must create session 0 (console) or die and therefore run winlogon in it. This change shouldn't have any effect on compatibility with Windows NT. smss will assume only csrss is critical. ea
