please understand: These apps are controlled by Microsoft Store server and NOT by language pack. You cannot change them
Thats normal since Windows 8.1 In Windows 8 every new app appears on metro but in windows 8.1 it only appears in "all apps" and you must add them to metro
Why partial: i've tried it and it works 100%. Only the metro app are still in english but it's becouse, as someone else said too, they're controlled by the store and not by the language pack. The rest of the system is fully translated
Guys I create a Windows 8.1 installations with integrated language pack dvd and this takes a bite until everything is perfect
The metro apps will be translate ? Beacause i've installed the fr pack, and everything is translate but no the metro apps.
