The problem you describe sounds - almost word-for-word - like the problem I had in Sep. 2016, and I posted my solution (a destructive forced install of the Windows Update) in the DC forum: Re: Windows 10 - if update does not work, try a forced destructive update.
If you look at that and the post I made immediately after, you will find some potentially useful links. There was no solution proferred in discussion forums, and I had at least twice run the system health check/cleanup for Windows 10:
- sfc /scannow
- Dism /Online /Cleanup-Image /RestoreHealth
If you have to take the same route, do ensure that you first take a copy of your current Windows 10 Product Key
, as you will probably need it after the install (if not before, when getting the ISO). The forced update/install is likely to be destructive of your existing Win10 image and will obliterate lots of stuff, so back up all your data, just-in-case, though it's the Programs
directories that mostly got zapped - the Programs
directories were largely deleted, and the User
directories were partially deleted with the residue being moved to an "Old Windows"
'Twas no picnic.
