Microsoft released an out-of-band update (KB5074976) on December 19 to address Message Queuing (MSMQ) errors caused by December 2025 security updates. These updates have led to operational disruptions in business applications and IIS websites, particularly on systems running Windows 10 22H2, Windows Server 2019, and Windows Server 2016, which received updates KB5071546, KB5071544, and KB5071543. Users reported issues such as inactive MSMQ queues, IIS sites generating "insufficient resources" error messages, and applications unable to write messages to queues. The problems stem from modifications in the MSMQ security model, which altered permissions for the system folder C:WindowsSystem32msmqstorage, requiring MSMQ users to have write access typically reserved for administrators. Systems with full administrative rights do not experience these issues. Microsoft is investigating the matter but has not provided a timeline for a resolution.

Microsoft has acknowledged a significant issue with the December 2025 security updates that disrupts Message Queuing (MSMQ) functionality, affecting enterprise applications and Internet Information Services (IIS) websites. The problem is prevalent among systems running Windows 10 22H2, Windows Server 2019, and Windows Server 2016 with security updates KB5071546, KB5071544, and KB5071543. Users are experiencing inactive MSMQ queues, IIS sites failing with "insufficient resources" errors, applications unable to write to queues, and misleading error messages about "insufficient disk space or memory." The root cause is changes to the MSMQ security model that altered permissions on the C:WindowsSystem32MSMQstorage folder, requiring MSMQ users to have write access to a directory typically reserved for administrators. Devices with users logged in as administrators are not affected. Microsoft is investigating the issue but has not provided a timeline for resolution. Rolling back the updates is a potential solution for administrators, though it carries security risks. This follows a warning from Microsoft in April 2023 about a critical vulnerability in the MSMQ service.

Microsoft has acknowledged issues related to the December 2025 security updates affecting Message Queuing (MSMQ) functionality on Windows 10 22H2, Windows Server 2019, and Windows Server 2016 systems. The updates KB5071546, KB5071544, and KB5071543 have caused problems such as inactive MSMQ queues, IIS sites showing “insufficient resources” errors, and applications unable to write messages to queues. These issues stem from modifications in the MSMQ security model, which now requires users to have write access to the C:WindowsSystem32msmqstorage folder, a privilege typically reserved for administrators. Systems with full administrative rights do not experience these problems, but this workaround is impractical for many enterprises. Microsoft is investigating the situation without a specified timeline for a resolution. Administrators may consider rolling back the updates, which poses its own security risks. In April 2023, Microsoft had warned about a critical vulnerability in MSMQ (CVE-2023-21554) that risked remote code execution attacks.

Modern antivirus solutions have reduced PC infections, but risks persist as cybercriminals develop stealthy methods to infiltrate systems. Signs of infection include unfamiliar programs, missing files, slow performance, and disabled security settings. If infection is suspected, disconnect from the internet, boot into Safe Mode, and run a full system scan with Windows Security or Microsoft Defender. To enhance cybersecurity post-infection, users should clear temporary files, reset browser settings, uninstall suspicious applications, scan external drives, keep Windows updated, use strong passwords, and verify sources before engaging with links or attachments. Tools like VirusTotal can help scan files from unverified sources. If performance issues continue, a complete reinstallation of Windows 11 may be necessary, ensuring essential files are backed up first.
