I just ran SFC /scannow and got his error message
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.
Should spend time trying to fix these issues?
If so, where do I begin? The CBS.log is Greek to me.
