Windows used to provide Interix which was a subsystem that allowed use to use quite a bunch of posix utilities and offered quite a very good integration with Windows. You could do quite a lot of things with it (we used it to convert a unix app to windows in record time) and it was IMO superior to Cygwin.

But that was 10 years ago, it disappeared at some point, being integrated somewhere in either the server version or the professional edition (named something like Unix Service for Windows) I lost track.

Considering all the work that MS is putting in interoperability those days, I'm wondering if it will not make a come back at some point.

Good luck with file permissions on the Windows host. You are in for a fun time.
