I i added the packages and some apps still wont change the language no matters if i pick another languageWindows default ("inbox") Appx's are multi-language packages, there are no local versions.
When you say "system apps", do you mean legacy Notepad and Paint? Those require optional CAB's to support other languages. Download and extract the optional FOD ISO, and install the app CAB's as an update.
can u help me how to solve the problem?
