Chocolatey is something you need if you've ever installed, upgraded, or removed software on Windows. It is an existing, proven, almost 4 year old project. For those familiar with *nix package managers, it is a binary package manager, sort of like yum or apt-get, but for Windows. 

Here's how the team describes the tool on their Kickstarter campaign:

Chocolatey is a tool that automates all the mundane getting and installing software work for you. You just select what you want installed and within a few minutes, Chocolatey has downloaded and installed (or upgraded) that software without need for further input from you. So while Chocolatey does the hard work, you can go get some coffee. Or sleep. Or do other more important things. 

You probably start to see why we like Chocolatey!

Chocolatey has been part of the NuGet ecosystem since forever, and we are happy Chocolatey users ourselves. From the very first beta of MyGet's package sources functionality, we have had built-in support for Chocolatey. In fact: if you're using MyGet Build Services, then you are already using Chocolatey! That's right: all the tools mentioned in our Build Services docs are provisioned on our build agents using Chocolatey!

We also know some of our users are using MyGet to host their own Chocolatey repository, which in turn is just another NuGet feed. It just serves Chocolatey packages instead.

It goes without saying that we are huge fans of the Chocolatey project and we really want to encourage and support the Chocolatey team to take the project to the next level. If you're like us and love Chocolatey, we'd like to invite you to join us in backing the Chocolatey Kickstarter project! MyGet has pledged $750 to help move the project from experiment to experience.

Chocolatey has proven to be a huge time saver and invaluable tool for us, and if you feel the same, the least you can do is to get yourself a nice box of chocolates ;-)

Let's get Chocolatey!
