SMSS.exe session management subsystem, it is responsible for starting a user session. This process is initialized through system processes, including reflection of the WINLON, WIN32 (CSRSS.exe) threads that have been running, and set system variables.

If something unpredictable occurs, smss.exe will stop the system to stop responding (that is, hangs). The CSRSS.exe subsystem server process, this is part of the user mode Win32 subsystem.
