Overview

This out-of-band update for Windows 10 Enterprise LTSC 2021 and Windows 10, version 22H2 includes fixes and improvements that address a known issue with Message Queuing (MSMQ) functionality. After installing the previous Windows updates released on December 9, 2025, some users experienced problems with MSMQ, such as message queues becoming inactive, insufficient resource errors, applications unable to write to message queues, and other related issues. This update resolves those problems, primarily affecting enterprise or managed IT environments. Individuals using Windows Home or Pro editions on personal devices were very unlikely to experience this MSMQ issue.

General Purpose

The update fixes problems that could lead to message queues becoming inactive, applications unable to write to message queues, error messages about insufficient resources, disk space or memory, and other related MSMQ failures. This issue primarily impacted enterprise or managed IT environments using the affected Windows 10 versions, while individual users on Windows Home or Pro were unlikely to experience these problems.

General Sentiment

Overall, this out-of-band update appears to be a targeted fix for a specific MSMQ issue that arose from the previous Windows updates. The sentiment around this patch is generally positive, as it resolves a problematic regression that was causing disruptions in enterprise environments. However, the fact that there are known issues present means that some caution is warranted, and IT administrators should thoroughly test the update before deploying it widely. The update is only applicable to specific Windows 10 versions, so its impact is limited compared to a more broadly applicable patch. But for those affected organizations, this update should provide welcome relief from the MSMQ problems.
