WAPT is an open-source package manager for Windows that's based on apt-get functionality and can ease the installation/updating/configuration/removal/management of Windows programs and drivers.

With being based heavily on the design of Debian's APT but for Windows, this project is called WAPT. WAPT has been under quite heavy development in 2014 and can be used to deploy software like Firefox and even Microsoft Office from a console. There's also the WAPTServer as part of this project for deploying custom software from a centralized console to many systems.

For those curious about WAPT to have apt-get-like functionality under Windows see the project site in French (or Google Translated to English). There's also this paper about WAPT.

For those in or around Brussels, at the end of month at the FOSDEM 2015 conference will be a presentation covering WAPT.
