Microsoft has released a new app called Language Community, which allows Windows 10 users to provide better translations for settings and apps in the operating system.

The idea behind the app is for people who use non-English language versions of Windows 10 to correct any mistranslations. This can be done quickly and easily by taking a screenshot of the text, then using the Language Community app to select the text and add your own suggestions for a more accurate translation.
