Well, "Windows Subsystem" is a term that has existed for like 25 years; the kernel design for NT included this idea of subsystems that could provide compatibility layers or other functionality at a lower level of abstraction than a user-space library. They thought they needed this when they splintered from the partnership with IBM in the OS/2 project. In the early days of Windows NT, Windows Subsystems for OS/2 and for POSIX existed as as well as the win32 subsystem. I think the POSIX subsystem eventually became Subsystem for Unix Applications (SUA) which did have some users at some point, though I was never one of them. I think they did borrow at least ideas if not code from that project for the Linux subsystem.

> I think the POSIX subsystem eventually became Subsystem for Unix Applications (SUA) which did have some users at some point... It had a bundle which had a NFS server or client, I don't remember. The only thing I remember is NFS functionality was a sure way to get BSODs. Every. Time. Towards end of its lifetime, SUA was re-purposed as a toolset to migrate UNIX environments to Windows, not to enable interoperability. The toolkit discontinued a year or two later IIRC.

Not with Windows shoehorned into the front? They were called “the X subsystem.”
