2021-05 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems (KB5003173) Failed to install - 0x800f0831

Hi all,

I've had the same cumulative update error for last month where the installation of this update would cause it to work up to 20% and then fail to install.

I've tried using sfc scanning and DISM restore and nothing is wrong with my computer.

This time the update installs to 100%, but then goes back to 0% and gets an error at 21% of the update.

EDIT 1:

I suspect that using a third party software called advanced system care may have cleaned up old driver packages, but I don't believe it affected the update because I've been using it for a while now and I didn't have any cumulative update problems in the past. Manually installing the updates do not work, neither does expanding the MSU files. The 0x800f0831 error has to do with missing package files.

EDIT 2:

I have done a repair install and it fixed my windows update problems, there does not seem to be any other way to fix the error.

EDIT 3:

I noticed my computer was stuttering and freezing much more than usual, so I booted into UEFI settings to put everything to default to see if that fixed it, my fans went full speed in BIOS mode for some reason. After settings are put to default, I restart my computer and now it's in an automatic repair loop.

EDIT 4:

The system restore was successful, but the real reason was because my laptop can not boot into default RST mode, so I booted into AHCI and it worked fine.

The only problem now is the quality update KB4023057 downloads and installs briefly every time I check for updates even though it was already successfully installed and updates the date it was installed.

EDIT 5: After downloading a .bat file from Reset Windows Update in Windows 10 | Tutorials (tenforums.com) and running it in safe mode the popup no longer shows up for KB4023057.
