This Windows Update error has plagued me for about a month and I have experienced it on multiple machines.
Thing I have done:
Tried installing standalone KB3000850 installer FAILED
SFC /SCANNOW GOOD
dism /online /cleanup-image /restorehealth FAILED
Beginning system scan. This process will take some time.
Beginning verification phase of system scan.
Verification 100% complete.
Windows Resource Protection did not find any integrity violations.

I am unclear of what else I can do besides start rolling back updates and trying to reinstall them or doing a system restore or doing a fresh install of Windows 8.1. None of those options are optimal for me, but alternative suggestions or solutions are appreciated
