Description:
The December 2025 Patch Tuesday update broke a few things - and the fix is
not yet done.

FULL STORY ======================================================================December
2025s Patch Tuesday updates broke MSMQ on Windows Server and enterprise Windows 10 systems, disrupting apps and IIS sites Microsoft is developing a fix but says affected organizations must contact business support for a workaround or rollback Reported issues include inactive queues, failed
writes, and false insufficient resources errors despite adequate capacity

Microsoft is asking businesses experiencing Message Queuing (MSMQ) issues to reach out directly to get assistance with a workaround.

The company recently released its December Patch Tuesday cumulative update, which seems to have broken MSMQ, causing issues in enterprise apps and Internet Information Services (IIS) sites.

MSMQ is a Windows service that enables applications to communicate by sending messages through queues. It allows reliable, asynchronous messaging between systems, even when they are offline, helping decouple applications and
improve resilience in distributed or enterprise environments. No timeline for a fix

The problems with the patch seem to affect Windows 10 22H2, Windows Server 2019, and Windows Server 2016 users with KB5071546, KB5071544, and KB5071543 updates installed. Private users dont seem to be affected by this - only business users.

"Individuals using Windows Home or Pro editions on personal devices are very unlikely to experience this issue. This issue primarily affects enterprise or managed IT environments," Microsoft said.

"A workaround is available for affected devices. To apply the workaround and mitigate this issue in your organization, please contact Microsoft Support
for business."

Microsoft said it was currently working on a fix, but its not yet complete. The company does not have a deadline or a timeline when it plans on releasing the fix, so it is possible that we will have to wait until January 2026s
Patch Tuesday batch, as well.

For now, IT admins who are experiencing these issues should contact
Microsofts business support department for assistance with a workaround, or even to roll back the installed updates.

In the call to businesses, Microsoft said it is aware of different problems following the patch, including inactive MSMQ queues, apps being unable to write queues, or sites returning insufficient resources errors. Some systems apparently are also returning "There is insufficient disk space or memory" notifications despite having enough resources.
