We aren't generating Chocolatey packages at the time of writing, though we have done so in the past.
For anybody who isn't already familiar with the technology, this is essentially apt-get for Windows - a global silent installer for tools.
We would like to support Chocolatey again in the near future for all the same reasons we support Homebrew on OS X and have PPAs for Ubuntu. For technically competent users, doing command-line operations like so would be very convenient: :
choco install cpp-ethereum
choco update cpp-ethereum
