How do I fix corrupt files with 'sfc /scannow' in Windows 8.1?

Question

I saw this question How do I repair the corrupted files found by sfc /scannow? "Windows Resource Protection found corrupt files but was unable to fix some of them.", but it was for Windows 7. Running the sfc /scannow command on my installation of Windows 8.1 gave me this error:

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.

I ran chkdsk and it found no problems.

Here is the complete log: http://sdrv.ms/1cOx19p

The reason why DISM can fix it, because Microsoft still doesn't provide the RTM files to download:

You need to point to the WIM file of the Windows 8.1 RTM DVD to get the correct files:

Dism /Online /Cleanup-Image /RestoreHealth /source:wim:D:\sources\install.wim:1 /limitaccess

(where D: is your Windows DVD drive or mounted Win8.1 ISO
