Microsoft POSIX subsystem is one of four subsystems shipped with the first versions of Windows NT, the other three being the Win32 subsystem which provided the primary API for Windows NT, plus the OS/2 and security subsystems.
UWIN from AT&T Research implements a POSIX layer on top of the Win32 APIs. MKS Toolkit , originally created for MS-DOS, is a software package produced and maintained by MKS Inc. that provides a Unix-like environment for scripting, connectivity and porting Unix and Linux software to both 32- and 64-bit Microsoft Windows systems.
The Windows NT operating system family's architecture consists of two layers (user mode and kernel mode), with many different modules within both of these layers.. The architecture of Windows NT, a line of operating systems produced and sold by Microsoft, is a layered design that consists of two main components, user mode and kernel mode.
They allow the operating system to run software developed for the platform in question. For example, Windows NT 4.0 has four environmental subsystems, for example Win32, DOS or Win16, OS/2, and POSIX, the latter of which is a Unix standard. [1] The latter resides primarily in the Dynamic Link Library posix.dll.

For example, Win32 is the major version of Windows API that runs on 32-bit systems. The name, Windows API, collectively refers to all versions of this capability of Windows. Microsoft provides developer support via a software development kit , Microsoft Windows SDK , which includes documentation and tools for building software based on the ...

The contents of the PEB are initialized by the NtCreateUserProcess system call, the Native API function that implements part of, and underpins, the Win32 CreateProcess (), CreateProcessAsUser (), CreateProcessWithTokenW (), and CreateProcessWithLogonW library functions that are in the kernel32.dll and advapi32.dll libraries as well as underpinning the fork() function in the Windows NT POSIX ...
