1. Cause and symptoms of language change errors
Symptoms after Windows language change
Some menus, apps, and system messages are still displayed in the old language
Text in the app is broken or translation is not applied normally
Different installed apps display different languages
Windows Store App, UWP App Mix Languages
Key causes:
Language pack not installed
App/Program’s separate language settings have not been changed
Regional (country, format) setting mismatch
Unupdated, System Cache/Temporary File Issues
2. Fixing problems quickly
Full language pack installation and default language settings
If some menus are not displayed normally after language changes, the language pack installation may be missing.
Settings > Time and Language > Language and Region (or ‘Language’)
Select the language you want from the list or click ‘Add Language’
Verify ‘Download Language Pack’ has been completed in ‘Options’ in that language
Change ‘Windows Display Language’ to the language you want
Reboot the system
Setting up and reinstalling app-specific language
Some apps have their own language settings, so change the language in the in-app settings or reinstall the app.
3. Verifying Language and Regional Settings
Match regional (country/format) and administrator options
Different language and regional (country/format) settings may cause some apps and stores to mix languages.
Set > Time and Language > Language and Region Match ‘Country or Region’, ‘Regional Format’ to the desired language area
Match by selecting ‘Change System Locals’ in Control Panel > Clock and Region > Region > Administrator Options
Apply Windows Update
The language pack and system module must be up to date to reflect the language change correctly. Install all the latest updates in Settings > Windows Update.
4. Advanced and additional troubleshooting methods
Clean up system cache and temporary files
If the menu does not change after the language change, clean up the cache and temporary files and reboot. Use the ‘disk clean up’ or cleanmgr command.
Reinstalling UWP/store apps
If the Windows Store app does not apply the language, uninstalling it and reinstalling it will reinstall it with the correct language.
Scan and recover system files
Corruption of system files may prevent language changes.Recover the file from the command prompt (administrator) to the sfc/scannow command.
