The Electronic Arts Download Manager or EADM for short is a small tool provided by EA when digitally downloading purchased games and software from the EA store. EADM also allows users to download, install and register their downloaded games, and easily keep all their game titles (digital or physical) up to date with the latest patches.

It comes with all new releases from EA, but exists as a separate tool and can installed and un-installed independently. To avoid using the EADM you will need to download and install updates manually. If a digital copy of a software title is purchased on the EA store, EA requires that it be downloaded through the EADM.
