POSIX Entries in the Registry

The POSIX subsystem starts whenever a user starts a POSIX application. The Registry entries for the POSIX subsystem are found under this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
    \Control\Session Manager\SubSystems

The Posix entry in this subkey describes the path to the executable file used to start the POSIX subsystem. The POSIX subsystem does not have any parameters or environmental variables that the user can set.
