I see it's already been mentioned
here, but I found it just recently when re-installing a Windows parition, and thought it deserved a little more exposure.
Let's get Chocolatey!
Chocolatey NuGet is a Machine Package Manager, somewhat like apt-get, but built with Windows in mind.
Easy Install!
To install chocolatey now, open a command prompt and paste the text from the box below and press enter.
c:\> @powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%systemdrive%\chocolatey\bin
