Solved Random language problems in Windows 11

Hi

I’m having a lot of language problems on my ASUS ProArt P16 laptop with Windows 11 Pro Version 25H2 (26200.7171). Some areas of a program do not recognise Danish characters like (æøå) while others work perfectly.

The Danish characters in the main menu in the screenshot below is shown correct but the movable menu below does not.



In the following screenshot of an installation process, the characters work perfectly in the installation window, but not in the license agreement window.



I have no issues on other computers, it’s just this one. It happens all the time in some applications while randomly in other applications. It seems to only happen when an application gets information from another source. So, it’s not the application itself that can’t show the Danish characters but when it shows them from a different source. I really hope this makes sense.

What I’ve tried:

A complete reinstall of Windows 11 Pro.

I’ve set every (that I know of) single language, zone, country, and keyboard setting to Danish/Denmark.

I really hope you guys can steer me in the right direction.

Best regards,
Bjørn

Hi Steve

Thank you for the suggestion, it was unfortunately already set to "Danish".

Best regards,

here is a link which shows how to change local system wide via the PowerShell

best of luck Steve ..

Do you have Microsoft 365 or Office Installed ?
If so check the lanaguge settings in one the apps.
Have you checked the correct keyboard is installed?

Thank you so much Steve.

The article had the solution for me. I ran Powershell as an administrator and used the command:

# Run as Administrator
# Set system locale to Danish (Danish)
$localeCode = "da-DA"

# Change system locale
Set-WinSystemLocale -SystemLocale $localeCode

# Optional: Set user culture and UI language
Set-Culture -CultureInfo $localeCode
Set-WinUILanguageOverride -Language $localeCode

# Restart to apply changes
Write-Output "Locale change requires a restart to take effect."

A quick restart later and it has fixed the issue.
