Windows 10 Update KB5012599 Failed to Install - Error Code: 0x800f0831

KB5012599 downloads 100%, then after a period of inactivity it pauses at Installing 20% for an extended period of time, after which it shows that it has installed 100%, but about a minute after that it generates the 0x800f0831 error with matching failure to install message.

I have spent the last 2 hours trying to fix this problem, including running the Windows Update Trouble Shooter plus a host of other suggestions, but nothing works.

Never had any issues with Windows 10 updates till now.

I don't know what to do.

Windows for home | Windows 10 | Windows update

    Yeah, KB5013942 won't install for me either. Behaves exactly the same as KB5012599.

    Guess we'll have to wait for 22H1 to drop (which is already late).

    I have exactly the same problem with KB5012599 – update says installed 20% and it freezes. Troubleshooter says “restart pending”, so I manually restart, it takes ages with blue screen then restarts. Installation resets to 0%, but then quickly returns to 20% - Groundhog day! Update history gives error code 0x800f0831

    Microsoft is supposedly working on a fix. Nothing is working on getting updates installed.
