Alternatives of Chocolatey in order to install "ROS on Windows"

edit

Hey,

I am using Kinect V2 sensor for tracking the human skeleton. And I would like to send the data(topic/message) to ROS in Ubuntu.

For doing that I would like to install the ROS on Windows to use it as a bridge between Ubuntu and Windows. But Unfortunately, I can not use Chocolatey, which is Windows Package Manager, because of our institute's security policy.

1. Is there any way to install the ROS on Windows without using Chocolatey?

2. And Is there any ROS package to make communication between Ubuntu and Windows?

Please let me know :) I will really appreciate it.
