I have tried the suggestions above and am still getting nowhere and this has been going on for months. I think the problem is that SFC shows errors which it can't repair. I also tried a startup repair which also failed. The errors in the log are pasted below. I also tried manually replacing the files which also had no effect. I have tried to contact Micrsoft support but they don't offer free support where I live.
POQ 84 ends.
