About the WIN Index above: The Index used above (2) is for the Desktop Edition, if you have a Server Core installation, please use 1:
dism /online /cleanup-image /restorehealth /source:WIM:d:\sources\install.wim:1 /limitaccess
Run Windows Update
Here should have been a screenshot of the successful command
“dism /online /cleanup-image /restorehealth /source:WIM:d:\sources\install.wim:2 /limitaccess”
-but you get the drift
A quick tip on sfc /scannow: if this hangs indefinetly you can go ahead and press ctrl+c
This wont’t break the check it will make the scan continue past the issue.
