It would seem the latest software update has killed my SurfaceRT. It now freezes on the home (tile) screen won't launch any apps (they don't respond to taps), can't switch into desktop mode. Its completely unresponsive. It won't scroll or respond to any finger presses. The keyboard won't even CTRL ALT DEL. Does anyone have any advice on how I might reset it? Or is it beyond rescue? In which case its going to be a very expensive paper weight.
