Not for Windows 1 through 3.11 or NT 3.1 to 3.51.

Vista will have a similar shell, however we are led to believe Vista was a rewrite from the bottom up as the code became too complicated.

Neither were built on UNIX. Linux is just the kernel at the heart of GNU/Linux distributions, Microsoft did sell Xenix for a while but Windows was originally a graphical DOS extender.
