Windows 11 PCs Fail To Shut Down After Update

Some users of Windows 11 have experienced a problem where their PCs reboot instead of shutting down after the Patch Tuesday security update KB5073455. This issue primarily affects devices with Secure Launch on Windows 11 version 23H2. Microsoft has confirmed this behavior, which disrupts the usual power-off sequence and can drain battery life for laptops and complicate remote management processes. An out-of-band update, KB5077797, has been released to restore normal shutdown and hibernation functionalities for affected systems. Users can check for this update in Windows Update or download it from the Microsoft Update Catalog.

Windows emergency update fixes MSMQ faults after December patchday

Microsoft has released emergency updates to address malfunctions with Windows Message Queuing (MSMQ) that occurred after the December security updates. The issues affect several versions of Microsoft Windows, including Windows 10 and various editions of Windows Server up to Server 2019, posing a risk of application outages for users relying on MSMQ. The problem arose from changes to the MSMQ security model, which modified NTFS access rights to the C:WindowsSystem32MSMQstorage folder, stripping applications or services without administrative rights of necessary write permissions. The updates are identified by knowledgebase numbers: KB5074976 for Windows 10, KB5074975 for Windows Server 2019, and KB5074974 for Windows Server 2016, raising Windows 10 build numbers to 19044.6693 and 19045.6693. Initially, these updates were not available through the standard Windows update function and could only be accessed via the Windows update catalog. Microsoft has expanded the list of affected systems to include earlier versions of Windows 10 (21H2, 1809, and 1607) and Windows Server 2012 R2 and 2012. Users of these systems should verify the application of December updates and manually install the emergency updates if necessary.

Microsoft patches bug causing multiple Message Queuing errors

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.
