As a "finished" OS, there are no more feature updates that risk breaking system configurations. Important Risks and Security Warnings
A common problem reported is that built-in Metro apps may not function correctly after installation. One user noted, "when I turn on applications such as Music starts to load and minimizes," and others corroborated issues with Internet Explorer, Bing, and the Microsoft browser. A workaround involved installing the English (en-US) AIO version and then adding the desired language pack.
