Bundled plugins do not come with a license and do not require activation or registration to use them with the theme. Please read more about it on Envato help center
The license notifications can be disabled from The7 > My The7 > Silence bundled plugins notification.
All bundled plugins can be updated via The7 > Plugins.
The updates of the bundled plugins can be postponed comparing to official updates. If you wish to access updates immediately after release, please consider purchasing them.
If you need to access their premium content – templates, add-ons, support from plugin author, and direct updates – you can buy a separate license for the plugins and register it.
In such a case, you will have to delete the bundled version and then install the standalone version.
