Unable to remove a language from Windows 10 April 2018 Update (version 1803)
Since installing the Windows 10 April 2018 Update (version 1803), I'm unable to remove a language from the Preferred Languages list in Settings, or from my keyboard language options. How can I remove these languages?
If you add a secondary language to Windows 10 version 1803 that shares the same base language as the Windows display language, neither language can be removed.
For example: If English (United Kingdom) is the current Windows display language, and you then add English (India) to the Preferred languages list, afterwards neither English (United Kingdom) nor English (India) can be removed from the Preferred languages
Note: The most notable effect of having multiple related languages in the Preferred languages list is additional entries in the text input selector. You can remove unwanted language
list entries using these steps:
1. From the Start menu, search for powershell.
2. Right-click Windows Powershell in the search results and choose
Run as administrator.
3. Type or copy/paste the following command at the command prompt, and then press Enter.
After typing this command, make note of the “LanguageTag” listed for the language you wish to remove, as you will need it in the next step.
4. Type or copy/paste each of the following commands at the command prompt, and then press Enter. In the following commands, instead of typing
<languagecode>, replace it with the language tag you wish to remove, such as
en-in for English (India).
