I'd like to see some evidence for that; without Unix, what would we be
running now? I doubt whether it would've been Linux, there being no
inspiration for it...
My vague (and rough) recollection is CP/M -> DOS -> Windows.
Even it has roots in Unix.
Only inasmuch as it has directories, users, and permissions (which any
semi-decent OS would have anyway)... Admittedly I have never compromised
my integrity by using/programming it, so I am willing to be corrected.
And yes, I know about POSIX compatibility, but so is Linux, and it's
different enough from Unix to be damned annoying.

Keep in mind that the MS-DOS 2 "handles" API for file access is based
*directly* on Xenix, and replaced the MS-DOS 1 "FCB" API borrowed from CP/M.
And also don't forget that Xenix had the largest UNIX installed base
measured by the number of machines it was installed on. People talking
about BSD and System V in the 80s, but it was Xenix that ruled on micros.
So at the time Microsoft offered both UNIX and MS-DOS.
