Maximum PC: "The Surface RT firmware update Microsoft made available last week as part of this year's first Patch Tuesday brought with it a number of improvements, including improved audio playback in Connected Standby and “additional capabilities for handling firmware updates during low battery situations.” But as with most firmware updates, there are always issues, known and unknown, that remain unresolved until a future update — or, as in this case, a simple registry hack — gets rid of them."
