Why does Windows 10 show mixed English and Vietnamese translations across all versions?

I installed the Vietnamese language pack from Microsoft Store on Windows 10, but the system still displays a mix of English and Vietnamese. When I checked the language files in System32/vi-VN and compared them with Windows 11, I noticed that Windows 10 is missing several Vietnamese language files. This seems to cause the system to switch inconsistently between the two languages. Even though I downloaded the Vietnamese language pack, the issue persists on all versions of Windows 10. However, Windows 11, Windows 8.1, and Windows 7 do not have this problem. Why is Vietnamese translation incomplete on Windows 10 while other versions work correctly?

    Hi Huy,

    Thank you for the update.

    Repair missing or corrupted files

    Open Command Prompt (Admin) and run:

    DISM /Online /Cleanup-Image /RestoreHealth

    sfc /scannow

    This restores system integrity and attempts to recover missing language components.

     

    Why This Happens in Windows 10

    Language support in Windows 10 for Vietnamese was never fully built out by Microsoft.

    Later OS versions (11, 8.1, 7) have more comprehensive localization, resulting in a smoother, fully translated experience.

     

    I hope this helps.

     

    Best Regards,

    Noel

    Hi Huy,

    Thank you for sharing your question. I get why it's annoying when you install the Vietnamese language pack on Windows 10, but some stuff is still in English, especially when Windows 11 and older versions do it right. You'd expect the translations to be consistent after installing a language pack. I am here to help.

    It looks like the problem is that the Windows 10 Vietnamese language pack doesn't have all the files to translate everything. Microsoft really made language coverage better in Windows 11. Older systems like Windows 7 and 8.1 used older files that had everything. So, Windows 10 is missing some files in the Vi-VN folder, making it show English for some parts.

    To fix this, here's what you can do, according to Microsoft and some people who've tried it:

    First, get rid of the Vietnamese language pack and reinstall it through Settings → Time & Language → Language. After reinstalling, make sure Vietnamese is the Windows display language. Also, set your Region to Vietnam.

     

    If you still see a mix of languages, try running a system health repair with DISM and SFC commands. This can bring back any missing or messed-up language files.

    I hope this helps.

     

    Best Regards,

    Noel

    The issue of mixed English and Vietnamese translations in Windows 10 may stem from incomplete language support in the operating system. While you have installed the Vietnamese language pack, Windows 10 may not have all the necessary language files that are present in newer versions like Windows 11. This can lead to inconsistent language display, where some elements are still shown in English due to the absence of corresponding Vietnamese translations.

    In contrast, Windows 11 and earlier versions like Windows 8.1 and Windows 7 may have more comprehensive support for the Vietnamese language, resulting in a more consistent user experience without the mixing of languages. The differences in language file availability across versions could explain why the issue persists specifically in Windows 10.
