Here's what you should have:

_vimrc:
filetype plugin indent on
OR
filetype indent on

C:\Program Files (x86)\Vim\vimfiles\ftplugin\markdown.vim: irrelevant

C:\Program Files (x86)\Vim\vimfiles\indent\markdown.vim:
(normal setup for an indent plugin, see a file chosen at random from
$VIMRUNTIME/indent)
(definition of Foldexpr_markdown)
setlocal foldmethod=expr
setlocal foldexpr=Foldexpr_markdown(v:lnum)

NOTE: a better place than C:\Program Files (x86)\Vim\vimfiles, is $HOME
\vimfiles. $HOME defaults to %HOMEDRIVE%%HOMEPATH% on Windows, but the
easiest way to see where it is, is to type from within Vim,
:echo $HOME

The same goes for the _vimrc.
