The '''DiscUpdate Disc''' is a disc used at authorized Nintendo repair centres. It installs an update on a Wii console via the [[Wii System Menu]]'s update mechanism, and verifies that the update has been installed using a special program ("boot-steve"). This disc was obtained and dumped by NWPlayer123 in late 2018.
   −
The disc installs its contents through an update partition, and the actual program on the disc is just a verification tool, unlike the [[Movie-Ch Install Disc]] which installs WADs on the disc itself.
+
While the disc does not have the autoboot value set in its ID, since it uses an update partition to install titles rather than an installer executable (like the [[Movie-Ch Install Disc]] and [[Wii Startup Disc]]), it can still function in the Wii Menu's recovery mode.
   −
Later versions of the [[Wii System Menu]] block this disc by its ID (similar to the [[Wii Startup Disc]] ID) for unknown reasons.
+
Later versions of the [[Wii System Menu]] block this disc by its ID, similarly to how the Wii Startup Disc ID is blocked. While the disc wouldn't have any purpose if inserted a second time after its first use, it's possible that it was blocked to avoid confusion or to encourage the disposal of the disc.

 +
The only known version of this disc installs Wii Menu v3.0U; it's unknown if other version and region variants exist, although this is implied by the version and region being mentioned on the disc's label.
