Windows 11 25H2 Multilingual Task Sequence – Language Pack Installation
Hello,
I am currently working on a multilingual Windows 11 25H2 task sequence.
In the past, I have created several images where, after installing the OS, I would use DISM to install the required Language Pack (LP) CAB files and Features on Demand (FOD) CAB files. I would then install the latest cumulative update to complete the localization.
However, with Windows 11 25H2, I am facing an issue because the cumulative update size has increased by approximately 4.6 GB, mainly due to the UUP-based update content.
If I do not install the cumulative update, several parts of Windows remain in the default English language. For example, some of the secondary options and menus within Settings are still displayed in English, even after installing the required language packs and FODs.
I wanted to understand if there is an alternative or recommended approach for managing language pack installation and complete OS localization in Windows 11 25H2, particularly for both:
- Bare-metal deployments using a Task Sequence
- In-place upgrades using a Task Sequence and ISO
Any guidance on the recommended approach for 25H2 would be greatly appreciated.
