I don't use windows, so I can't give an informed answer, but my guess is
that perhaps the windows environment lacks ptys (pseudo-ttys)?

When Emacs in unix opens a shell session, it uses a pty to talk to the
inferior shell.  A pty appears to the shell to be a normal terminal, but
is actually controlled by Emacs.  When Emacs _can't_ create a pty for
some reason (e.g. in unix you can run out of ptys), it falls back to
using a normal pipe to talk to the subshell; this works mostly, but will
_not_ appear like a terminal to the shell.
