DISM Error 0x800f081f
Thank you for this useful information.Sorry for being late to give you an answer. I also saw that "kyhi" gave you instructions on how to go about a repair install and I think that's not what you want to do. If you go that route, you will have to reinstall all your data files. Now, having said that, If you do want to upgrade Windows 10 within Win 10 like I did, follow instead these instructions:
-After burning your .iso files from the downloaded Media Creation Tool, leave the DVD inside the CD-DVD drive and don't reboot.
-Open windows Explorer and double-click on the CD-DVD drive, which should open a new window with all the files you have just burned. Look for the setup.exe file and double-click on it. That should start the installation of Windows 10. Let it run till the end, which normally takes a while.
-When the installation is thorough, remove the DVD from the CD-DVD drive, reboot your PC and run sfc /scannow again to see if you still have the dreadful error (0x800f081f). If not, that means the upgrade was successful. All you have to do at this point is finally to check for new Windows Updates.
One last word of caution is to make sure you have a good system image backup before starting.
I really hope that answers your question.
It worked nicely.
