Answer 2

After installing the December 2025 Windows security update, users may face issues with Message Queuing (MSMQ) functionality. A workaround is available for affected devices. To apply the workaround and mitigate this issue in your organization, please contact Microsoft Support for business.

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

Answer 3

Hi 56004744,

A reliable workaround is to restart the Message Queuing service and ensure that dependent services (such as Distributed Transaction Coordinator) are set to start automatically. In some environments, re‑registering MSMQ components or applying the latest cumulative update released after December has resolved the behavior. I recommend confirming that your systems are fully patched and monitoring for the upcoming hotfix, which will provide a permanent resolution.

You can try and let me know the update. If this explanation is useful, please tick “Accept Answer” so I know your concern is resolved. Thank you!
