    This is a great solution both technically and in clarity of presentation; thank you, thank you. I was having repeated failures installing Windows 8.1 update KB2919355 (the giant, critical rollup) on my Asus Transformer via both Windows Update and direct download and installation. Nothing on Microsoft’s or Asus’s websites was any help. I did steps 2 and 3 above, rebooted, and it installed without a problem.
