Question about DISM error message

[mikemyers]

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.

 

a) 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?

Yes, the files that you need are on your Windows DVD.

 

Insert your Windows disk and run the sfc /scannow from the command prompt.

The files should be automatically replaced from the DVD.
