Patch Tuesday written with Windows logos

Microsoft has announced the availability of KB5010419, the Patch Tuesday update for Windows 8.1 and Windows Server 2012 R2. Unlike the Windows 11 Patch Tuesday update, which has a slender set of release notes, the Windows 8.1 update has quite a long list of notes and issues.

Improvements and fixes

This security update includes improvements and fixes that were a part of update KB5009624 (released January 11, 2022) and update KB5010794 (released January 17, 2022). Additionally, this update also addresses the following issues:

Updates daylight savings time to start in February 2022 instead of March 2022 in Jordan.

Addresses an issue in which virtual machines (VMs) on a Windows server that has Unified Extensible Firmware Interface (UEFI) enabled fail to start after installing the January 11, 2022 Windows update.

Addresses an issue in which Windows stops running with an IRQL_NOT_LESS_OR_EQUAL error.

Addresses an issue in which a Lightweight Directory Access Protocol (LDAP) modify operation that contains the SamAccountName together with the UserAccountControl attributes fails with “Error: 0x20EF The directory service encountered an unknown failure.”

Adds an audit event on Active Directory domain controllers that identifies clients that are not RFC-4456 compliant. For more information, see KB5005408—Smart card authentication might cause print and scan failures.

Aside from this list of improvements, there are also two known issues in this update, here they are and the methods to work around them.

Symptom	Workaround
Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.	Do one of the following: Perform the operation from a process that has administrator privilege. Perform the operation from a node that doesn’t have CSV ownership. Microsoft is working on a resolution and will provide an update in an upcoming release.
After installing updates released January 11, 2022 or later updates, apps using Microsoft .NET Framework to acquire or set Active Directory Forest Trust Information might fail, close, or you might receive an error from the app or Windows. You might also receive an access violation (0xc0000005) error.	To resolve this issue manually, apply the out-of-band updates for the version of .NET Framework used by the app.
