Windows 11 ships with a massive list of preinstalled applications and background features that you will likely never use, but manually removing them is tedious and risky. Tiny11 Builder is a free, open-source utility designed to solve this exact problem by letting you create a lightweight, debloated Windows 11 ISO before you even run the setup.
With its newly redesigned WinUI interface, the application makes customizing Windows installation images incredibly straightforward. It supports three flexible build modes—Tiny11, Tiny11 Core, and Custom—allowing you to strip away unwanted components safely while keeping the system fully serviceable and stable.
