I can quote:
"Windows Update says the only available update is KB2919355 but the update size is stated to be a mere 37KB.
Attempting to install the update sometimes results in failure with error code 80246013, or more commonly claims to have succeeded, but then just lists the exact same update again after checking for more updates.
Downloading and running the offline installer for KB2919355 gives the error, "This update is not applicable to your computer", as does the installer for KB2919442 which is supposedly a prerequisite."
