Q: How can I launch the installation of Windows features that have been removed from Windows via Features On Demand?

A: Windows has a tool, fondue.exe, that allows the enabling of optional features that have been removed from an installation, which it will pull from Windows Update or whatever configuration has been specified via Group Policy.

Run fondue.exe without any switches to see detailed help on its capabilities and how to avoid any visible notifications (e.g., /hide-ux:all).
