Abstract: A technique allows a user to project content onto a shared display region in a controlled manner. The technique involves receiving context information that describes a context in which a user is currently interacting with a local user computing device. The technique then determines, based on policy logic and the context information, whether it is appropriate to invoke a private state, or to remove the private state and enter a shared state. The private state involves presenting a privacy screen on one or more shared display regions. The local user computing device remains connected to the display device(s) that host the shared display region(s) while operating in both the private state and the shared state. According to one advantage, the technique eliminates or reduces the risk that the user will inadvertently release private information to others; further, it does so without asking the user to perform burdensome preparatory actions.

Abstract: Managing user accounts on a shared computing device to maintain at least one of system resources or performance. The method includes identifying one or more desired triggers indicating that that one or more user accounts should be deleted from the shared computing device to comply with a predetermined resource target. The method further includes, as a result of the one or more triggers, deleting user accounts to attempt to comply with the predetermined resource target.

Abstract: Updating a computing device. The method includes identifying a defined computing system role for the computing device. The method further includes, based on the defined computing system role for the computing device, identifying a schedule for performing maintenance tasks for the computing device at the computing device corresponding to the defined computing role for the computing device. The method further includes performing one or more maintenance tasks for the computing device according to the identified schedule.
