A few more comments to what Ge van Geldorp wrote.

Nature has no sort of own documentation I am aware of... but it is an
excellent project! Many books were written later about it. ROS is just a
few picoseconds after the Big Bang... ;)

At this point, do not confuse that kind of session with a typical
Unix/Windows user session. SM sessions are "emulated operating systems".
At present, ReactOS boots only the emulated Win32(tm) session
(CSRSS.EXE). We hope it will be able to boot more in the future.

Recently, in an attempt to clean the design a little to make the SM
support easily other OS emulators, loading of WIN32K.SYS and running
WINLOGON.EXE were moved in CSRSS.EXE.
