The Wii U System Software, also known internally as Cafe OS,[5] is the official operating system used for the Nintendo's Wii U home video game console. Nintendo maintains the Wii U's systemwide features and applications by offering system software updates via the Internet. Updates are optional to install, but may be required in order to retain interoperability with Nintendo's online services. Each update is cumulative, including all changes from previous updates.

The system's official integrated development environment, named MULTI and published by embedded software engineering vendor Green Hills Software, is intended for use by Nintendo and its licensed developers in programming the Wii U. Details of the operating system's internal architecture have not been officially publicized.[6]

The Wii U operating system is split into 2 parts: One, normally displayed on the Wii U GamePad upon startup is the Home Menu, acting as an application organizer and launcher. It is a graphical shell similar to the Wii's "Wii Menu" and Nintendo 3DS HOME Menu. It allows launching software stored on Wii U optical discs, applications installed in the internal memory or an external storage device, or Wii titles through the system's "Wii Mode". The other, officially named the "WaraWara Plaza" is displayed on the TV screen. It displays the 8 most popular Miiverse communities and posts in a layout similar to the Mii channel's Mii Plaza on the Wii. The two screens' display roles can be swapped with the press of a button.

Like the original Wii, discs can also be hot-swapped while in the menu. The Wii U Menu may also be used to launch applications entirely beyond just gaming: the Miiverse social network which is integrated with all games and applications; the Internet Browser for the World Wide Web; play media through Netflix, Amazon Video, Hulu, YouTube, and more; download Wii U software and content through the Nintendo eShop; and receive official notifications from Nintendo.[7] System settings, parental controls and the activity log can also be launched through the menu.
