In order to solve the “DISM /Online /Cleanup-Image /RestoreHealth” error 0x800f081f, you must specify a valid Windows image file (install.wim) that contains all the files needed from the repair process. The install.wim file is contained in any Windows installation Media under the “sources” folder (sources\install.wim).

Note: The install.wim file must be of the same Windows Version, Edition and language as the installed Windows version.
