TITLE   :INF: Disabling the POSIX Subsystem
PRODUCT :Windows NT
PROD/VER:3.10
OPER/SYS:WINDOWS
KEYWORDS:

The information in this article applies to:
 
 - Microsoft Windows NT operating system version 3.1
 - Microsoft Windows NT Advanced Server version 3.1

There is little to gain by disabling the POSIX subsystem in Windows NT
because POSIX is only started once a POSIX-based application is
started. There are no memory savings or performance increases.
 
If you want to disable the POSIX subsystem, you can do so by going to
the following subkey and deleting the POSIX value:
 
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
   Session Manager\Subsystems
 
Note: The same is true for the OS/2 subsystem; until an OS/2-based
application is started, the OS/2 subsystem server is not loaded.
