The trick to a successful DISM though is matching the broken system's patch level with that of the source files. DISM basically repairs your component store using the source, so for it to work properly, you'd want to use the same OS patch level store as the source. I used to keep a few good Windows VMs at different patch levels for this purpose. I'd then patch the VM up to the same level as that of the broken machine (if needed), and then use the good VM as the DISM source.
In any case, if DISM keeps failing, then a repair install (aka in-place upgrade) usually does the trick.
