Como corrijo arquivos corrompidos com 'sfc / scannow' no Windows 8.1?

Question

Eu vi esta pergunta Como faço para reparar os arquivos corrompidos encontrados pelo sfc / scannow? "A Proteção de Recursos do Windows encontrou arquivos corrompidos, mas não conseguiu corrigir alguns deles." , mas foi para o Windows 7. Executar o comando sfc /scannow na minha instalação do Windows 8.1 me deu este erro:

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.

Eu corri chkdsk e não encontrei problemas.

Este é o registro completo: link

O motivo pelo qual o DISM pode consertá-lo, porque a Microsoft ainda não fornece os arquivos RTM para download:

Você precisa apontar para o arquivo WIM do DVD do Windows 8.1 RTM para obter os arquivos corretos:

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

(onde D: é sua unidade de DVD do Windows ou ISO Win8.1 montado
