In fact, I did not see anything in that thread that addressed CBS.log

I read through that thread but do not know how to "go into the CBS.log and find the repair attempt and summary." What steps do I follow?

The ...RestoreHealth command gets this result: Error: 0x800f081f That's looking much better than I thought. So now you should go into the CBS.log and find the repair attempt and summary Here's an example http://answers.microsoft.com/en-us/windows/forum/windows8_1-windows_update/windows-81-store-error-0x80070002-comprehensive/2b0ed3e1-1835-4517-97dd-0a7abb6ef74c?page=3

and the Scannow results: C:\WINDOWS\system32>sfc /scannow Beginning system scan. This process will take some time. Beginning verification phase of system scan. Verification 77% complete. Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not supported in offline servicing scenarios. C:\WINDOWS\system32>

The ...RestoreHealth command gets this result: C:\WINDOWS\system32>Dism /Online /Cleanup-Image /RestoreHealth Deployment Image Servicing and Management tool Version: 6.3.9600.17031 Image Version: 6.3.9600.17031 [==========================100.0%==========================] Error: 0x800f081f The source files could not be found.
