You can't disable or uninstall any core components such as com_content
. They are protected. I'm not sure of the exact things that require com_content
, however completely removing it which would have to be done by deleting the folders and removing any reference to it in the database could possibly and most likely result your site malfunctioning. It's therefore protected for good reason ;)
I do know that in either Joomla 3.5 or 4.0, there will be an option to install core components with installing Joomla.
