In favor of the more capable mcandre/windows box:
https://app.vagrantup.com/mcandre/boxes/windows
$ vagrant box add -f mcandre/windows-chocolatey
$ cd <project>
$ vagrant init mcandre/windows-chocolatey && vagrant up
$ vagrant ssh
>choco -v
0.10.3
https://atlas.hashicorp.com/mcandre/boxes/windows-chocolatey/
$ time make box
...
Then manually create, version, upload, and release the new box on Atlas.
