Microsoft admits Windows 10’s extended updates are causing issues, MSMQ won’t work
Microsoft has acknowledged that the December 2025 Patch update for Windows 10 (KB5071546) is causing issues with MSMQ (Message Queuing). This problem primarily affects businesses as consumer PCs typically do not have MSMQ installed. The update has altered how MSMQ functions, impacting its security behavior and permissions. Users experiencing MSMQ issues are advised to uninstall the problematic update and pause updates until a fix is available. Microsoft is investigating the problem and has confirmed it only affects Windows 10, not Windows 11.
