tiny11 Core 26H1 Build 26300.9550 Preactivated

Software Overview

---

tiny11 Core 26H1 Build 26300.9550 is a reduced Windows 11 build based on the Windows 11 2026 update platform. The source describes Windows 11 version 26H2 as using the same servicing foundation as versions 25H2 and 24H2, allowing eligible systems to receive the release through an enablement package.
The tiny11 Core edition goes further by removing additional Windows components. The build removes the Windows Component Store (WinSxS), disables Windows Defender, and excludes Windows Update because the absence of WinSxS prevents normal servicing. Windows Recovery Environment (WinRE) What's New content is also removed.
