See System Default UI Language of Windows 10  

Hi Shaun

Hope you're well buddy!
Assuming I already have the language pack I need installed.
If I run "Dism.exe /Online /Set-AllIntl:en-gb"
Would that work to set the default?

Many thanks in advance.

That's great.

Cheers mate.

Hi, I just noticed a strange setting in the Registry:
HKEY_CURRENT_USER\Control Panel\Desktop\LanguageConfiguration

Name: nl-NL
Value: en-US

I live in Belgium, the Dutch speaking part (nl-BE), and when I downloaded/installed the latest Windows version I noticed that the language was set to Dutch - Netherlands. There was no option to select another language during installation so I continued. ..

Afterwards I installed the en-US language pack.

Can someone more knowledgeable than me check if these settings in the screenshot below look normal?

Ok thanks Shaun!

Hi Shaun,

Background for my problem:
I bought a desktop computer from Germany. It came with Windows 10 pre-installed and with German localization (de-DE). I have changed the UI language to en-US so now I can actually use my system since I speak or write no German!

My problem:
When I boot to Advanced Startup options from Settings in Windows (Settings > Update & security > Recovery > Restart now under Advanced startup), it opens with all text in English (good!).
If I then click > Troubleshoot > Command Prompt, it switches to German, and asks to select a user account and enter the password, all in German.
When I then exit Command Prompt and it returns to the Advanced Startup options, this time all text is in German in the Advanced Startup options and stays in German until I boot back to Windows.

I have a similar problem when I boot from the Recovery Drive that I have created. In this case everything (all text) is in German.

My question:
How/where can I change the language in Advanced Startup when opened from Settings in Windows?
And how/where can I change the language in the Recovery Drive?

By the way, this switching to German in Advanced Startup does not occur if I boot from a WIM USB and from there enter Advanced Startup. I assume because when you create a WIM, you specify the language for the WIM, which in my case was en-US.

Thank you for your time Shawn!

Thanks Shawn - but I have checked/double-checked all steps in that tutorial and "English (United States)" is shining everywhere.

I have gone even one step further.
The Registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\Language
was showing:
Default REG_SZ 0409
InstallLanguage REG_SZ 0407

I changed InstallLanguage from 0407 (de-DE) to 0409 (en-US) and it is still switching to German in Advanced Startup!

If you have no other ideas/suggestions, I will give up and use only the WIM USB.
Thank you.
