The disclosure is directed to presenting a unified view of tasks and applications across multiple computing devices of a user. A unified view of the tasks can be presented using a task manager. The task manager presents a list of tasks that are executing at each of the devices. The user can perform multiple actions on the tasks, e.g., launch on a first device a task executing on a second device from the first device, or terminate from the first device a task that is executing on the second device. A unified view of the applications can be presented using an app tray. The app tray displays a list of apps installed on each of the devices of the user. In displaying the list on a particular device, the app tray displays the apps that are not installed on the particular device in a distinct format, e.g., as shadow icons.
