Thanks, overall it LGTM but has two minor suggestions.

Also, can you please run gen-windows-sys-binding locally to make sure it works with the changed location?

Ah yeah, it needed a little adjustment since moving gen-windows-sys-binding to the dev-tools directory in #927. Now it works regardless of how you run gen-windows-sys-binding.
