It hasn’t been the best few days for users of the Windows 10 operating system, what with the newly-reported emergence of an old bot attack threat, and Patch Tuesday confirmation of a Windows kernel zero-day vulnerability that requires all Windows 10, 11 and Server users to update as soon as possible. Now, you might not think that’s too problematic, despite Windows 10 now being out of support, thanks to the availability of Microsoft’s Extended Security Updates programme. Think again. Microsoft has now admitted that some Windows 10 ESU users are unable to install the latest security update rolled out as part of Patch Tuesday. Here’s what you need to know.

Along with the likes of the National Security Agency and America’s Cyber Defense Agency, more formally known as the Cybersecurity and Infrastructure Security Agency, I have been banging the update Windows as a matter of some urgency when security issues are confirmed drum for the longest time. Unfortunately, sometimes Microsoft makes this harder than it ought to be. Issues with Windows security updates failing should never occur, but they do. The latest confirmation comes from Microsoft itself, “Some Windows 10 devices enrolled in Extended Security Updates (ESU) might fail to install the November 2025 security update,” Microsoft said, adding that this can lead to “error 0x800f0922 (CBS\_E\_INSTALLERS\_FAILED).”

I have reached out to Microsoft for a statement and further advice for users, but in the meantime, it would appear that this issue is only impacting business users with Windows 10 devices that have corporate licenses. “This issue is isolated to devices activated via Windows subscription activation through the Microsoft 365 Admin Center,” Microsoft said. There are, to the best of my knowledge, no workarounds for this ESU security update failure currently, with Microsoft omnly stating that “The issue is under investigation, and additional information will be shared as soon as it becomes available.” Likewise, please return to this article as I will update it when this situation changes or an official fix is available.
