To check the health (You would use /CheckHealth to only check whether the image has been flagged as corrupted)
run Dism /Online /Cleanup-Image /CheckHealth
To scan the health use /ScanHealth to scan the image for component store corruption. This option does not fix any corruption.
run Dism /Online /Cleanup-Image /ScanHealth
To RESTORE health (recommended)
Use DISM /Online/Cleanup-Image/RestoreHealth to scan the image for component store corruption, perform repair operations automatically, and records that corruption to the log file. This generally takes 15-30 minutes depending on the corruption and size of the partition
You can run scanhealth & restore health at the same time like this
DISM.exe /Online /Cleanup-image /Scanhealth && DISM.exe /Online /Cleanup-image /Restorehealth
After running DISM it is a good idea to re-run SFC /scannow to make sure all the issues were fixed.

The ISO must be exactly the same version as the running OS. An ISO of 10586.0 will not repair a running system of 10586.35 because it has additional updates and files.
DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:SourcesInstall.wim:1 /LimitAccess Where 'X' is the drive letter where the ISO is located. Simply change the 'X' to the correct drive letter
If you do not have an ISO you can make one. The instructions are hereIf this wiki has proved helpful please click me too at the bottom of the wiki.
