A new desktop application for the Tiny11 Builder project streamlines the creation of minimal Windows 11 installation images, reducing reliance on PowerShell scripting. The tool, designed to produce leaner ISO files by removing bundled applications and optional system components, accepts Windows 11 installation media from version 22H2 onward, including 26H2. The resulting images are significantly smaller than Microsoft's default installations.

The primary update introduces a WinUI 3-based graphical interface that wraps a rewritten C# image builder, supplementing rather than replacing the original PowerShell scripts. Users can choose from three build configurations: a standard Tiny11 mode that removes most preinstalled apps while preserving Windows Update, Defender, and recovery features; a core variant that disables updates and security tools and permanently strips additional components; and a custom mode allowing selective inclusion or exclusion of specific elements. The core configuration is explicitly discouraged for production use, with developers advising its restriction to test environments due to irreversible modifications and potential loss of critical functionality.

Microsoft does not endorse these modified images, and licensing requirements remain unchanged despite the reduced footprint. The project's maintainer emphasizes that no alterations bypass Windows activation obligations. While the tool offers enthusiasts greater control over system composition, its use involves trade-offs including potential security vulnerabilities, lack of official support, and compatibility risks with future Windows updates. As documented in the project repository, bypassing hardware requirements or account creation prompts is not guaranteed across new builds. The development reflects ongoing community efforts to customize Windows installations, though users should weigh the technical benefits against the associated maintenance challenges.
