The first step is to get Ruby and RubyGems running on Windows. We recommend RubyInstaller for a quick one-click solution, and this is the solution we support. There are, however, other methods to getting Ruby running on windows.
Once Ruby and RubyGems are installed, install Vagrant with a single command:
C:\> gem install vagrant
Finally, as with other platforms, you will need to have downloaded and installed Oracle’s Virtualbox for Vagrant to run properly. Vagrant will verify this when it is first run.
With Vagrant installed, you can now follow the remainder of the getting started guide just like any other Vagrant user and everything should work the same across all operating systems, including Windows.
