Tiny11 Builder, a tool for creating debloated Windows 11 installation images, now has a desktop app preview that lowers the barrier for enthusiasts. According to The Register, the main change is a WinUI 3 application built around a new C# image builder, rather than simply wrapping the existing PowerShell scripts in a graphical interface. The tool accepts Windows 11 installation media from 22H2 onward, including 26H2, and produces a considerably more compact ISO.

The app offers three build modes. The standard Tiny11 mode removes bundled apps while retaining Windows Update, Defender, and recovery tools. Tiny11 Core goes further by disabling updates and Defender and irreversibly removing components, including the recovery environment. A custom mode lets users decide which Windows elements to keep or drop from the ISO.

The project's author is clear about the trade-offs: the resulting ISOs are not supported by Microsoft, and Tiny11 Core is recommended only for test virtual machines. The repository also notes that local-account and hardware-check settings are "best effort" and not guaranteed on newer builds. As with earlier versions, a Windows license is still required—no modification bypasses licensing or activation.
