I am trying to use dism/online/cleanup-image/restorehealth tool in an elevated command prompt to fix corrupt files that sfc/scannow is unable to repair. I keep getting this error message below:
Microsoft Windows [Version 6.2.9200]
(c) 2012 Microsoft Corporation. All rights reserved.
Deployment Image Servicing and Management tool
The online/cleanup-image/restorehealth option is unknown.
For more information, refer to the help by running DISM.exe /?.
The DISM log file can be found at C:\WINDOWS\Logs\DISM\dism.log
