Windows 8.1 update 1 _KB2919355 Error: 0x80070070

While I have been pootling about updating machines at home I received an  Error: 0x80070070 for _KB2919355 patch. After some digging the problem and a bit of trial and error was the need for 4.5 Gb of free space to be available which on some of our smaller tablets was a challenge.

But simple enough, clear the space and you are set to go
