You can download LuaTeX v0.85 built for Windows from the w32tex site,
but that is probably best to use with TeX Live not MiKTeX (the TL
binaries are those from w32tex). However, there are *big* 'under the
hood' changes in v0.85 and adjustments to parts of the LaTeX build
system are needed as a result. Those aren't yet on CTAN so you'll need
to do some work. See https://github.com/josephwright/luatex85 but note
that this really is *for developers*. (The intention is to address this
in the next LaTeX release, likely nominal date 2016-01-01.)
