The first version of Windows NT (3.1) was only released in 1993. That makes it rather easy to surpass the capabilities of Unix back in 1989...
There are many more features in Windows that come from Unix and other OS's than vice versa. E.g. proper multi-user functionality.
Perhaps you'd care to provide some specific examples of ideas that originated at Microsoft rather than somewhere else first. Your list will either be horribly short, contain dubious innovations or be ignoring prior art.
