this is a next gen system. read the manual and electronic manuals. every app has its own electronic manual available in the menu of that app.
don't worry, u can turn off the Wii U also, when u turn it on it will give you a message that new software have been installed.
operating system updates are the only ones that need confirmation to install.









Enjoy the U! Its only going to get better! Did you get the NSMBU bundle? or wat?
