Updating Drupal core in a Acquia Dev Desktop? Running the latest Acquia Dev Desktop (with subscription) with Drupal 7.22 core.

I´d like to update the Drupal core to the most recent version, but after reading the documentation on Acquia that is available to unsubscribed users, I wonder if that is at all possible. Any ideas on how one would go about this?
The Acquia documentation for Dev Desktop lists very clearly the steps that need to be taken to upgrade your Drupal install: https://docs.acquia.com/dev-desktop/upgrade.

Also, if you are a subscriber, you can open a ticket with them and they will assist you.
