After each patch day just update using the launcher.exe in each folder and it will update just fine and only require the patch to be downloaded once. It will be saved in a common folder and be used to update each folder of wow. Just open the launchers one at a time.
I don't understand what is being said here about the common folder and only downloaded once. Can anyone clarify this?
