Use DISM to Repair Windows 10 Image  

@tomcat--
Yes, burned DVD from ISO. It sounds like you are saying it does not really matter whether I use the DVD or the mounted ISO. I can update to AU either way. It seems OldMike prefers mounting the ISO. Makes sense, saves a DVD or flash drive, but I already have a DVD, so I might as well use that. Be a few days before I can make a backup and get to it.

That's true. You can do either. I've got several machine OS's and if I don't get the update thru Windows in a timely fashion, I usually use Rufus to put it on a thumb drive (same as burning a DVD) and update the others with it. Your choice. ISO mounted from a separate drive is the best choice, though, in your case. I will mention to you one thing. If you use the DVD, after it has finished configuring all the files it needs, the machine will restart. If you still have the DVD in there, it may try to boot from it. When you see that getting ready to happen, eject the DVD. If you miss that chance, you'll probably get a message at the top of your screen that says "Press any key to boot from CD". DO NOT DO THAT!!! Let it go normally, and after it starts the process, eject the DVD. Sounds confusing, I know, but that's why mounting the ISO (on separate drive) and running from that is a lot more foolproof.

If I've totally confused you, I apologize. Sorry.....

Okay, not really a problem. The machine we are currently discussing is a laptop, so that drive will probably pop out when it finishes. If not, I'll keep my eye on it--I know what to do. I do also have another laptop and two desk machines to update pretty soon, so I will particularly watch out with the desktop machines. I didn't want to mess with those (which have not given corruption msgs.) until I understood what is going on with my laptop.

BTW, because the laptop has such a weak onboard display, I have not been geared to go to Nvidia for a driver. I just don't expect much from it anyway. But I think I also have Nvidia in the desktop machines, so I may try doing that more with those.

Downloaded the latest iso from the Media Creation Tool
Win10_1607_English_x64.iso

Mounted that file, drive J:
The install.wim was located in J:\Sources, so: J:\Sources\install.wim


I then used
Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:J:\sources\install.wim:1 /limitaccess



but still got an error:

Error: 0x800f081f
The source files could not be found.

In case of a mounted ISO, is the instruction different then?
(mounted using Windows Explorer)



Last question:
Can version 1607 be used to repair 10586.545 ?

Thanks

@tfwul ... The ISO downloaded using Media Creation Tool is in a compressed format, referred to as ESD format. It will not work correctly with DISM. It is fine for installing and doing in-place repairs, but not for DISM. You must use the WIM format ISO from this link: Windows 10 ISO

Lots of people use the incorrect format and get the error. Many wonder why does MS have two different ISO's. It can get confusing. The contents of the two formats are identical, the only difference is the size of the ISO. The MCT (highly compressed ESD) is about 600-700MB smaller than the un-compressed WIM. MS has supplied two different ones to reduce download times, especially on metered connections. The ESD is the generally used format, but will not run correctly with DISM work.

Hope this clears up the error for you. Download using the link above, and you should be good to go!

And to answer your question: Last question:

NO

Hi,
I have the same problem as tfwul, I used the wim format ISO from the link you gave but dism still can't locate the files.
The ISO I've downloaded indeed does not have the same build number as my operating system (ISO is 1607, my system is 10586.545), but this is what I get from the download site. Do I need a different version of the ISO? Where can I get it?
Thanks
