Microsoft warns of Windows issue causing updates to fail


Microsoft is warning users of a Windows Update bug that affects all versions of the operating system from Windows 8.1 to current Windows 11. In an article on the Windows Health Dashboardthe issue also affects client and server versions of the platform.

In the article, Microsoft explains that the problem prevents Windows from installing the recent version Security Update for Secure Boot DBX (KB5012170). When someone tries to apply the update, Windows Update shows error code 0x800f0922.

To clarify, this is a bug related only to the Secure Boot DBX patch. While this is part of the August 2022 Patch Tuesday release, other security updates, feature releases, and monthly fixes are unaffected by the bug.


According to Microsoft, it has instructed its engineers to investigate this bug and will release a fix in an update. However, the company does not say when this update will arrive. In the meantime, there is a way around the bug.


Of course, avoiding the KB5012170 update will allow you to avoid this problem. However, if you want the Secure Boot DBX patch, 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 view information about these bugs spanning 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 disrupted by updates or configuration issues. Many start their PCs only to find that their Microsoft Store isn’t working or their Windows apps won’t open. Luckily, Windows 11 and Windows 10 have an automatic repair feature for apps that can fix such issues.
