If a disc won't play properly, start by checking the disc.
Nintendo didn't design the Wii to support homebrewing.
So, there's no guarantee that using homebrew software won't harm your Wii.
As a result, the community is curious to see what changes have been introduced in the new Wii U update 5.5.4 U but the official support website doesn’t seem to offer any insight on it for now.
Since Wii U was hacked wide open and anyone who had access to it could use the method to make their Wii U support running backups, Nintendo has usually tried to combat this issue by releasing a new firmware update.
You also may be prompted by Windows XP or Windows Vista to allow the download or installation of the software with a warning that Windows XP or Windows Vista does not recognize it.
Sometimes, a Wii or Wii U is unable to read a disc; other times, a game will freeze or crash.
To prevent Nintendo from automatically updating your system, turn off Wii Connect24.
To do so, select Options, then select Wii Settings. Also, prevent new games from attempting to update the system.
All of these minor updates have been released within a short while of each other but without any noticeable improvements to consider updating the system.
