OS/2 subsystem in the architecture of Windows NT

The NT POSIX subsystem was included with the first versions of Windows NT because of 1980s

4.0
were certified as compliant with FIPS 151-2.

The

runtime environment
of the subsystem is provided by two files: psxss.exe and psxdll.dll. A POSIX application uses psxdll.dll to communicate with the subsystem while communicating with posix.exe to provide display capabilities on the Windows desktop.

The POSIX subsystem was replaced in Windows XP and Windows Server 2003 by "Windows Services for UNIX",[2] (SFU) which is based in part on OpenBSD code and other technology developed by Interix, a company later purchased by Microsoft.[3][4][5][6] SFU was removed from later versions of Windows 8 and Windows Server 2012. SFU is logically, though not formally, replaced by the Windows Subsystem for Linux[7] (WSL) in the Windows 10 Anniversary Update and Windows Server 2016 Version 1709[8][9] respectively.
