2. Where to Get a Windows 11 Multi‑Language ISO

• Problem: If you integrate language packs into an RTM (Release to Manufacturing) build of Windows 11 (e.g., 22000), and later a Cumulative Update (LCU) is released, the LCU contains delta updates for English only.
• Result: The system can fail to install the LCU (Error 0x800f081f) because the language binaries no longer match the update hash. The solution requires using the latest base ISO (e.g., 22H2 or 23H2) before adding languages.
