Message Queuing (MSMQ) might fail with the December 2025 Windows security update
| Status | Originating update | History |
|---|---|---|
| Confirmed | OS Build 19045.6691 KB5071546 2025-12-09 | Last updated: 2025-12-12, 17:13 PT Opened: 2025-12-12, 17:13 PT |
After installing the December 2025 Windows security update (KB5071546), users might face issues with the Message Queuing (MSMQ) functionality. This issue also impacts clustered MSMQ environments under load. Due to this issue, users might encounter the following symptoms:
- MSMQ queues becoming inactive
- IIS sites failing with “Insufficient resources to perform operation” errors
- Applications unable to write to queues
- Errors such as "The message file 'C:\Windows\System32\msmq\storage*.mq' cannot be created” when creating message files
- Misleading logs like “There is insufficient disk space or memory", despite sufficient disk space and memory being available
This issue is caused by the recent changes introduced to the MSMQ security model and NTFS permissions on C:\Windows\System32\MSMQ\storage folder. MSMQ users now require write access to this folder, which is normally restricted to administrators. As a result, attempts to send messages via MSMQ APIs might fail with resource errors.
Next Steps: We are investigating this issue and will provide more information when it is available.
Affected versions:
- Client: Windows 10, version 22H2
- Server: Windows Server 2019, Windows Server 2016

Certain laws require Microsoft to protect children from harmful and illegal content on the internet. Microsoft is committed to creating tools for parents and guardians to help them in guiding their children’s digital experiences and protect them from harmful and illegal online content.
One of the available tools is web filtering, which lets a parent or guardian filter websites. Currently, Microsoft Edge is the only supported browser that provides this functionality within Microsoft Family Safety, allowing Edge to be used by default on the child’s device after web filtering is enabled. Once web filtering is enabled, a parent or guardian needs to approve other unsupported browsers (any browser other than Edge) before they can be used. This helps parents understand that different settings apply to other browsers when it comes to blocking inappropriate websites and filtering search results for their children.
The blocking behavior continues to work for unsupported browsers, however, when unsupported browsers update to a new version, the latest version of the browser cannot be blocked until we add it to the block list. Microsoft is currently adding the latest versions of unsupported browsers, to the block list. As a result, some browsers may temporarily appear unblocked during this update process. We're actively working to ensure all latest versions of browsers are blocked, reinforcing our commitment to parents and guardians.
As Microsoft continues to update the block list, we’ve received reports of a new issue affecting Google Chrome and some browsers. When children try to open these browsers, they shut down unexpectedly. However, the standard workflow is to prompt a parental approval message stating, “You’ll need to ask to use this app”. Once the approval is consented, the browser operates as intended. This issue is only observed when the Activity reporting feature is turned off.
Workaround: The browser shutdown issue can be temporarily mitigated by turning on Activity reporting under Windows settings in Family Safety. Parents will then be able to receive approval requests as expected.
Resolution:
- Temporary access to unsupported browsers: As of June 25, 2025, Microsoft included the latest versions of unsupported browsers into the Family Safety’s feature, and they are now blocked as intended. However, new versions of unsupported browsers released after this date might temporarily appear unblocked. This temporary gap will be resolved in the future, and this documentation will be updated to inform you when the full resolution is available.
- Missing parental consent prompt: Fixed in the July non-security preview update (KB5062649), released July 22, 2025. The fix is gradually rolling out and will be automatically enabled on devices with KB5062649 installed or later updates.
Affected platforms:
- Client: Windows 11, version 24H2; Windows 11, version 23H2; Windows 11, version 22H2; Windows 10, version 22H2
- Server: None
