    Not sure I fully understand step 6. To use DISM......... and: The install.wim file will be in the Sources folder of a mounted Windows 10 ISO file.

    To do step 6. I have to first download a Windows 10 ISO? (If this is correct I assume it is to have a place to get a non-corrupted/missing file from...or?)

    sfc /scannow = found corrupt files it could not repair.
    cleanup-Image /Scanhealth = said component store is repairable.
    Dism /Online /Cleanup-Image /RestoreHealth = said Error: 0x800f081f The source files could not be found....

    (I noticed that in updates that Security update KB3074683 failed to install today???? the problem??)

    so my next step has to be download a Windows 10 ISO ?

    or is the Windows 10 "Go back to Windows 8.1" a viable option - but only if it is a real clean easy option (= don't lose stuff, have all kinds of problems, driver issues, or whatever problems)??? The only reason I think about doing this is because a) to have a clean re-install of Windows 10 (assuming I can re-install), b) this time to install in German (where I live) and be able to use audio Cortana (now I can't because I installed in English) = but this is only worth it if I can do this WITHOUT loss or even more problems!

    glad of help / clarity on this - and my thanks


    Hello xyz,

    Step 6 and Step 7 is to be able to have DISM use the image from a clean ISO file to repair the component store with instead when you are not able to use the Windows image from step 5 if corrupted.

    However, many have not been able to get past the Error: 0x800f081f without having to clean install Windows.

    Thanks for a quick reply

    does this mean that the "Return to Windows 8.1" is then a viable/better option??

    or is this too going to give me lots of problems (or not possible due to this problem)? (= scared of starting this if I only lose things, only have more problems, driver issues, or can't get back to W10 re-install, etc.)

    I did also make a AOMEI Backuper system backup (windows 8.1) the day before I upgraded - can i restore this ? or is it better to use the Return to Windows 8.1 option 0 or are non of these an option?? (sorry my knowledge is too limited)

    You could try going back to 8.1, and upgrading to 10 again if you like. A clean install will give you better results though.

    Okay there is another option - (sorry I edited my last Post too late before you answered)

    I have a AOMEI Backuper system backup (windows 8.1) made the day before I upgraded - can i restore this ? (never done this before but...!)

    Then I would start all over again wouldn't I (with a clean upgrade)?

    (Don't feel easy with the doing clean install = a clean install means installing the system completely new without being able to keep everything on my computer = or?)

    Sure, you could do that as well. As long as you get back to an activated 8.1, you'll be able to upgrade to the free 10.

    Okay Brink, I want to really thank you for your time and help.

    Not quite sure what I should do for the best - wish I did not have to do anything, but I do - not sure either why an AOMEI Backuper system backup (windows 8.1) restore would not give me an activated Windows 8.1, it is a backup of how my system was - and it seems like the best solution for a computer dummy like me (bit worried the Windows 10 Restore option might not work properly - and the clean install sounds too complicated for my expertise)

    any way thanks a lot - really appreciate it

    Even doing a clean install of Windows 10 gives corrupt files. Dism seems useless in Windows 10 or in it's current build. I've tried all suggested steps and doing a clean install as a last resort and still get Error: 0x800f081f.

    So if the official ISO and upgrade from Microsoft is corrupted, how would someone fix this issue? The reason for me using Dism was because I was getting errors using Windows image backup and powershell giving errors, not sure if there's any other issues.

    To be honest I am not quite sure what is meant by “clean install” – so when you do a normal upgrade from Windows 8.1 (or Windows 7 etc) is this a “clean install”? or is a “clean install” only when you install on a totally clean (formatted) drive (like having a new computer with no system on it)?

    Well anyway:

    I had three computers to upgrade: a Windows 8.1 Desktop (where I now get the 0x800f081f), my sons Desktop Windows 7, and a small Medion 29,5 cm Notebook with Windows 8.1

    After finding the problem with my Windows 8.1 Desktop I ran scans on the other two - Result:

    My sons Windows 7 Desktop = found no problems at all

    Medion 29,5 cm Windows 8.1 Notebook = Problem (corrupt files that could not be repaired) = but = Dism /Online /Cleanup-Image /RestoreHealth = solved the problem = two further scans have not shown any problem returning

    So not sure what I can make of this? I wonder if the upgrade can be corrupted when at least one computer has no problem – but why do two others have corrupted file problems – and why does one of these let itself be repaired – and the other one not ??????

    At the moment I’m still stuck (afraid to make things worse, get even bigger problems or lose things) in deciding the solution/next step: Above LittleJay says “...so I restored a W7 image and it is still activated...” and since I had made the AOMEI Backuper system backup (windows 8.1) I will probably try to get over my fear and try restoring this....and hope for the best!

    Has anybody used the Windows 10 default one month “Go back to Windows 8/8.1/7” option? Results?

    EDIT: Just thought of something (probably nothing but will mention it)!

    The Windows 7 computer was a pure original Windows 7 install
    The other two are both updates/upgrades from Windows 8 to Windows 8.1 ( and both still have a factory Windows 8 restore installed)? (but still would not explain why one lets itself be repaired and the other gets 0x800f081f)

    Correct. A clean install is when you wipe the drive to be unallocated, then select the unallocated drive to install Windows to.
