Hello gegjr,

I'm Jin, a fellow Windows 10 user and an independent advisor. I can see that you are getting an error 0x800f0831 when updating KB4556799.

Since you have already tried running DISM, check if by clearing the cache and manually downloading the update will help you.

1. Restart computer and boot up in Safe Mode. To boot to safe mode: https://support.microsoft.com/help/12376/
2. In Safe Mode, Run command prompt as Administrator.
3. Type: net stop wuauserv and hit Enter.
4. Type: net stop cryptsvc and hit Enter.
5. Open file explorer and go to C:\Windows and find SoftwareDistribution and delete this folder.
6. Go back to command prompt and type: net start wuauserv and hit Enter
7. Type: net start cryptsvc and hit Enter.
8. Restart your computer.

Select the exact update to download and install.

If this doesn't work, try updating using the Media Creation Tool:
https://www.microsoft.com/software-download/win...

1. Click the "Download tool now" button.
2. Once downloaded run the MediaCreationTool1909.exe file.
3. Accept the terms.
4. Select Upgrade this PC, then hit Next.
5. Proceed with the prompts.

I hope this helps.

I ended reinstalling Windows 10 by choosing the reset option and allowing Windows to only keep my files and delete everything else.

 This of course meant I had to go through the ENORMOUS TROUBLE of reinstalling my programs of which I have several.

I am NOT happy with Microsoft!

I finally gave up and just reinstalled Windows 10! Of course it's a pain but I did the "reset" option which left my files, although not an issue as most my important stuff on a cloud, but I had to reinstall all my programs which are pretty numerous. I then let all the updates run and it seems to be running fine now. However, I had a minor hiccup a couple of days ago when one update had an error, don't remember what, but it did finally install. So far so good for 3 or 4 days.

I have same issue. So Ms i think its time to fix it not just  let everyone reinstall windows.

And why make so many updates all time ? And one thing is test it before letting it mess up people computers.
