Data (such as software or save data) saved to USB storage media or SD Cards will no longer be usable.
Deleting all content and settings will not revert the system software to a previous version.

Be aware that you will not be able to redownload any games that are no longer available for purchase or download.
Any linked Nintendo Network IDs will not be deleted when deleting users. The Nintendo Network IDs that were being used before deleting all content and settings can be reused by linking them to new Wii U users.
- Any Nintendo Network IDs that were linked to Wii U users on the console cannot be used on other Wii U consoles.
- Your Nintendo eShop purchase history and balance are saved to your Nintendo Network ID. If you link an ID you were using with Nintendo eShop to a new user after deleting all content and settings, you will be able to redownload your purchased software free of charge.
