I know that The Elder Scrolls Online is automatically updated.
But other games that also have this Auto-Update feature are already detected by VulnDet (for example Elite Dangerous or Star Citizen).

The makes it comfortable for players to download larger patches/updates for games when they don't want to play.
So the update can be downloaded while users are working or not actively use the PC and when they want to play the game they don't have to wait until an update is installed.
