I go this error when doing sfc /scannow and was wondering what is was about. Any help greatly appreciated. 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 cant upload my CBS.log file because it says that it is empty, even though t isn't.
