Hello,

Windows 7 Update KB3071756 will not install completely.

sfc /scannow finds errors that it cannot repair. Here is the log: (not sure if I've used SFCFix.exe correctly)

Hello and welcome

Due to the precise nature of your corruption, you will receive help from a user named LiquidTension. He's one of our senior trainees here who's in his final phrase of his studies and needs to gain some real world experience in specific areas of Windows Update. This means that he'll be assisting you, but that I will first need to double check and approve his fixes before he posts them to you. If anything this is a good thing for you because it means that you've got at least two of us watching over your thread, but it will unfortunately add a slight delay between each reply. I hope that you understand and can accept the need for us to train up new members in this way in order to carry on doing what we do here, however, if for any reason you object to this setup, I will happily take on your thread myself.

Thank you very much for your understanding. We'll be with you very shortly.
