Is this Possible to check Operating System Language through Command Prompt ?
The way I found to achieve something similar is to check if Windows is in English or in Portuguese by checking the environment variable with the Program Files path.
In Portuguese: "Arquivos de programas"
In English: "Program files"
How to do it:
To check if Windows is in Portuguese (Brazil):
@echo %PROGRAMFILES%|find "Arquivos de programas" > NUL
if errorlevel 0 echo Windows is in Portuguese
And in English:
@echo %PROGRAMFILES%|find "Program files" > NUL
if errorlevel 0 echo Windows is in English
So, at least you can check if Windows is in a specific language, as long as you know what the programs folder is called in that language.
Notice: the path is case sensitive. If you put "Program Files" with an uppercase "F", it won't find anything. Correct is all lowercase.
To ignore case, use the /I switch in the FIND command.
