Developed WSL and discontinued SFU (Windows Services for UNIX), which they had since NT 4 days.

SFU 1.0 and 2.0 relied on the MKS Toolkit by MKS/PTC, and SFU 3.0 later adopted the Interix (OpenNT) subsystem, which Microsoft acquired from Softway Systems in 1999.

The original POSIX Subsystem (psxss.exe) was Cutler's team who implemented a minimal POSIX.1 subsystem server alongside Win32 and OS/2. This was done primarily to satisfy US Federal Government procurement requirements (FIPS 151-2).

		True, though to Microsoft's credit, the existence of the POSIX subsystem, even as a proof-of-concept, ensured the underlying kernel design supported the development of products like Interix, just as Windows on Alpha et al. ensured NT remained reasonably portable to future platforms like ARM, unlike say OS/2 where the only non-Intel release (for PowerPC) was basically a prerelease lacking core OS features like networking.
