Over the last few years we've had a wide variety of questions about removing Drupal modules, including these:
- Do I need to remove modules via the admin or the file system?
- Do uninstalled modules leave database entries behind?
- Can I just disable a module, rather than completely uninstall it?
- Should I uninstall Drupal core modules when I see that option?
Robert answers all those questions and more in this video from our Drupal Security class.
