When trying to download and install updates, users often encounter the error code 0x800f0831. There are also those who encounter reboot problems.
And although the problem is not common, it also appeared relatively long ago. In other words, even in a five-month post on the Feedback Center site, the problems experienced during the installation process of the Windows 11 update are mentioned.
It’s worth noting that Microsoft is aware of the issue and is “trying to do its best to resolve Windows Update issues, including including SSUs (Service Stack Updates) in the monthly cumulative update.” But the latter, unfortunately, did not help.
