Microsoft has acknowledged that Message Queuing (MSMQ) may fail on certain Windows 10 devices and older Windows Server versions after the December 2025 Security update. Reported issues include MSMQ queues becoming inactive, IIS sites generating "Insufficient resources to perform operation" errors, and applications failing to write to queues. System logs may show misleading messages about insufficient disk space or memory due to folder permissions and MSMQ's write access requirements. The root cause is linked to changes in the MSMQ security model and NTFS permissions for the C:WindowsSystem32MSMQstorage folder, which now requires write access typically restricted to administrators. This issue primarily affects Windows 10 versions 22H2 and earlier, as well as Windows Server versions 2012 to 2019, with minimal impact on Windows Home or Pro editions. Microsoft recommends contacting support for workarounds, and some users have resolved the issue by uninstalling the update, though this would remove security enhancements. The problems are confined to older operating systems often used by enterprises delaying upgrades.
