A frequently used tool to identify Windows issues is the System File Checker, or sfc. It’s usually run as such:
sfc /scannow
This will scan through your system files and tell you if any files are corrupt. But — is there an easy way to repair those corrupt files, other than doing a full re-install? Turns out, there is: Connecting to the Internet, and using dism, as shown below:
dism /online /cleanup-image /restorehealth
See below for a copy-paste log that I did on the system I’m currently using to write this post. SFC identified corrupt files, I ran dism, and then re-ran sfc.
C:\WINDOWS\system32>sfc /scannow Beginning system scan. This process will take some time. Beginning verification phase of system scan. Verification 100% 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.
