I frequently used DISM.exe on running W8 and W8.1 x64bit operating systems. The command was always written as: “>dism /online /cleanup-image /restorehealth”. I never got an error message and never used “/Source” as part of the command.
With W10x64 recently using >dism /online /CheckHealth and >dism /online /ScanHealth, the results indicated “repairable corruption” in the both the image and the componentstore. But, when I ran DISM as written above in paragraph one, I got the following error message:
“Error: 0x800f081f
The source files could not be found. Use the /Source option to specify the location of the files that are required to restore the feature.”
When working with W8.1, it was my understanding that DISM.exe would use Windows Update to retrieve most current files to repair any corruption to the online image. Windows 10 seems to need additional DISM.exe arguements to find current files to repair the corrupted files.
Q. With W10, do i need to specify a /Source location for Windows Update?
Q. Do I need to specify the /Source location for an .ISO file or the 10586 USB thumbdrive I have, to repair my running online image?
My PC is running Windows 10-10586.
thanks
