Abstract: A computing device comprising a computer program executed on a processor of the computing device, including: a rendering module configured to read stored instructions to display a graphical user interface, the stored instructions including code for a plurality of focusable GUI elements, each focusable GUI element having an associated identifier, a focus map module configured to store a precomputed focus map including a focus map entry for each focusable GUI element indicating, for that focusable GUI element, for a plurality of predetermined navigation directions, a target identifier of a target focusable GUI element for that navigation direction, a user input module configured to receive a user input of a predetermined navigation direction, a focus module configured to query the precomputed focus map with an identifier of a currently focused GUI element and the predetermined navigation direction to retrieve and move focus to the target focusable GUI element.

Abstract: High-performance streaming installation of software applications can be achieved by pre-fetching chunks of application files. Pre-fetching can be directed by a recipe file that can handle a wide variety of application behaviors. If a missing chunk is encountered during execution of the application, a cache miss record can be created and forwarded to a telemetry server. Cache miss records can be aggregated to generate a revised recipe file so that future installations of the application avoid the missing chunk scenario. Using the revised recipe file can cause fewer interruptions, result in less delay and otherwise improve performance.
