Winget is a command line tool that allows discovery and installation of applications, which will eventually make its way to mainline Windows 10. As I set up a new machine every couple of weeks, it's handy to have a batch file to run from the command line and install a bunch of tools, utilities and languages I use all the time.
You can install the winget preview appx here, and there are more options described here if you want to go the Windows Insider route.
