MBAM is clean - good. That rules out anything lurking on the system.
For the installed apps, here's what I would like to see removed:
Here's what I would like to see updated:

PocketCloud Wyse Technology 12/1/2013 15.2 MB 2.6.21
(Dell Digital Delivery and PocketCloud are part of Dell - if he buys software and downloads through Dell, he'll need this, otherwise not.)
Shared C Run-time for x64 McAfee 9/7/2013 2.76 MB 10.0.0
(I don't see McAfee AV, so I don't think this is needed and may be a leftover from a long time ago.)
On the Dell support site, you can download the updates one at a time, and when you go to install them, they will tell you if they are not needed, so don't worry about checking the rev of every driver to see if you need it or not. It also will tell you if a component is not installed if you try to install a driver for something that's not on the system.

I will get you the link(s), and have a look at the available updates for this system later this evening, but I think this may help...have to see what's there.
It's my understanding that you can do all three DISM commands pointing to the WIM, but I could be mistaken. I'll have to check on that. Do those two run without pointing to the WIM? If so, what are the results? And the third one, RestoreHealth, does that complete when pointing to the WIM? Are you using a v1511 WIM ISO for that?
Okay, the ISO you are downloading, that is the v1607, the latest (Anniversary Update), right?
Okay, probably not a result of anything anyone did. I suspect an update coupled with an old driver of some sort may have something to do with it, but wanted to check if anything specific had happened, just for clues. I may have more specific ideas once I have a look at the Dell support page.
The Macrium image is not for me - it's for you, or rather your friend, in case we are unable to correct this, or something goes terribly wrong, or we determine that a clean install is the only solution. Of course, I'm trying to avoid that, as I'm sure your friend will prefer a fix rather than a clean install...So, I'd like to have that done before anything else, as a little "insurance policy". I hope you have some room on an external hard drive for the image?
