Installation instructions for Windows don't work

[lebeg]

In the Installing MXNet in Windows instructions there is a paragraph:

Installing the Prebuilt Package on Windows
MXNet provides a prebuilt package for Windows. The prebuilt package includes the MXNet library, all of the dependent third-party libraries, a sample C++ solution for Visual Studio, and the Python installation script. To install the prebuilt package:

Download the latest prebuilt package from the Releases tab of MXNet.
Unpack the package into a folder, with an appropriate name, such as D:\MXNet.
Open the folder, and install the package by double-clicking setupenv.cmd. This sets up all of the environment variables required by MXNet.
Test the installation by opening the provided sample C++ Visual Studio solution and building it.
This produces a library called libmxnet.dll.

Issues

• There are no Prebuilt Packages published at the mentioned Releases page
• The mentioned setupenv.cmd can nowhere be found

Sure, thanks @yajiedesign. The documentation needs to be updated anyway.
