I can't change my "Default system UI language" thoroughlly

Question

As you can see. I've tried everything I can get from Internet. Such as system Language&region setting (As you can see, I've already delete languages except English, but it still shows when I click the check box), PowerShell (I've already delete other languages by using "Set-WinUserLanguageList $LangList -Force"), and Regidit (Follow instruction of https://www.nextofwindows.com/remove-display-language-windows-11). Anyway, everthing I can tried. But when I typed "DISM /online /get-intl" in CMD, it still shows "Default system UI language : zh-CN". I really have no idea what I can do to fix it.

Hi Werson,

After changing the registry edit, before rebooting, you may try an in-place upgrade using the en-US ISO.

However, before doing so, please take an image-based backup of the current configuration and store it in another drive or partition.

Answer 3

Dear Ramesh,

Thanks a lot for your reply.

I've already tried to change the default registry value to "0409" and "en-US", but it didn't work, and after a reboot it changed back to "0809".

I ended up using the "zh-CN" installer package to update my computer from 22H2 to 24H2 to keep my applications and files.

Best wishes.

Hi Werson,

Please see if changing the default OS language in the registry helps.

First, please backup the registry using AceLogix RegBak.

Create a System Restore Point.

Open Regedit.exe.

Change the "Default" value to 0409 in this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\Language

(Note: 0409 is the Locale ID for English United States.)

Restart Windows.
