An UI override language is a language that takes residence over your defined language list. It took a little while to work out, but I’d set a UI override language in the classic Control Panel.
New language packs could also not be installed from the classic Control Panel. However, I ran into a situation where Windows no longer offered the option to install a language pack. If you’re running low on disk space, you may need to initiate the download manually. After adding a new language to the list, Windows will install a language pack for the selected language. You can normally install language packs from within the Windows Settings app: Time and Language: Region and Language: Language list.
In Windows 10, you can install language packs for free with any edition of Windows at no upgrade cost. In older versions of Windows, you were stuck with the language the license was bought with – or you could install extra language packs if you’d paid extra for the Windows Professional edition. Language packs translates and localizes Windows 10 into different languages. Here is how to restore the ability to download additional language packs after having locked in an UI override language on a Windows 10 device.
The split between the Control Panel and the Windows Settings app can cause some weird situations.
