I have two Windows PC's both running Windows 8.1 - they both have an issue that apparently needs to be corrected with 'dism'.
After doing the "SFC /scannow" repeatedly, they always find an error.
I did:
dism /online /cleanup-image /checkhealth then
dism /online /cleanup-image /checkhealth and finally
dism /online /cleanup-image /restorehealth
After all this, on both machines, I get an error message "The source files could not be downloaded.", and then "Use the "source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see "http://go.microsoft.com/fwlink/?LinkId=243077".
Then it tells me where the log file can be found.
---------------------------------------------------------------------------------------------
Here are my questions. I have read that dism's first choice is to download new versions of the corrupted files, using "Windows Update". Is this correct?
Next, if the above is true, why can't dism do this from Windows Update when I can manually download other updates?
Finally, I have found a lot of information that I don't understand regarding using the "source" option, but noplace can I find a clear set of instructions for how to do this.
Are the needed files still someplace on my PC? If so, where, and once I know where, what would I type in the following, which I think is what I need to do:
dism /online /cleanup-image /source???????? /restorehealth
And last, can I simply insert the Windows CD in my computer, and find the needed files there?
I have read threads here with the same question, but they were resolved by the user posting the log files, and someone here sorting out what the errors are. I plan to do that later tonight, but from everything I've read, 'dism' is supposed to find out what the files are, then download un-corrupted versions of them, then replace the bad files with correct files. It is supposed to get them from "Windows Update". I would prefer to learn how to do it this way, so I'll be able to help with other people's computers with a similar issue.
(It's a year old version of Windows 8.1 on one PC, and a reasonably up to date version on the other. One is at work, the other at home.)
