Windows 11 22H2 update fails with error 0x800f0806, here are possible fixes

As suggested in reports, Microsoft released Windows 11 version 22H2 to the public channel on September 20th. You can read all about the exciting new stuff in these articles here. A few days before, some users received an early feature update for 2022 with new devices. The machines shipped with build 22621.521 (KB5017321), which was indeed the 22H2 update, as Microsoft later confirmed.

However, since the release, many have been reporting issues and issues when trying to upgrade to Windows 11 22H2. According to these reports, the update fails with an error code of “0x800f0806”. Apparently it happens when trying to do an in-place upgrade via Windows Update in Settings due to some kind of compatibility issue or something similar. Clean install though seems to work fine.

Luckily, Reddit user rap1021 found a solution to the problem. Apparently, manually downloading and installing the update works around this issue caused by trying to update via Windows Update. To do this, simply go to the Microsoft Update Catalog website and download the update.

Other known solutions such as running “sfc /scannow” via the command line or resetting the Windows Update mechanism do not seem to work, according to the same user, and downloading the update manually seems to be the best choice.

Another user, CusiDawgs, in the same thread says that the latest Windows 11 Setup Assistant also works. You can download it from the official Microsoft website here .
