Microsoft is warning users of a Windows Update bug that is affecting every version of the OS from Windows 8.1 to the current Windows 11. In a post on the Windows Health Dashboard, the issue also impacts both client and server versions of the platform.
In the write-up, Microsoft explains that the issue is preventing Windows from installing the recent Security Update for Secure Boot DBX (KB5012170). When someone tries to apply the update, Windows Update surfaces a 0x800f0922 error code.
To clarify, this is a bug related solely to the Secure Boot DBX fix. While that was part of the August 2022 Patch Tuesday release, other security updates, feature releases, and monthly rollups are not affected by the bug.
According to Microsoft, it has put its engineers on the job of investigating this bug and will issue a fix in an update. However, the company does not say when that update will arrive. In the meantime, there is a way to bypass the bug.

Of course, avoiding the KB5012170 update will allow you to avoid this issue. However, if you want the Secure Boot DBX fix, you can update UEFI (Unified Extensible Firmware Interface) to the latest version to install the update without incident.
Microsoft is also investigating/handling a bunch of other known issues related to this month's Patch Tuesday. You can check out information on those bugs covering Windows 11 and 10 through the Windows Health Dashboard.
Tip of the day: For the most part, Windows apps are stable, but they can still be still thrown out of whack by updates or configuration issues. Many boot their PC to find their Microsoft Store isn't working or their Windows apps aren't opening. Luckily Windows 11 and Windows 10 have an automatic repair feature for apps that can resolve such issues.
