General Sentiment

The general sentiment towards this update appears mixed. While it includes important security fixes, there are reports of issues arising after installing the patch, particularly related to the Message Queuing (MSMQ) functionality. Users have experienced problems with MSMQ queues becoming inactive, IIS sites failing, and applications unable to write to queues. The root cause is attributed to recent changes in the MSMQ security model and NTFS permissions, which now require MSMQ users to have write access to the C:WindowsSystem32MSMQstorage folder, normally restricted to administrators. This primarily affects enterprise or managed IT environments, while individual users on Windows Home or Pro editions are less likely to encounter the problem.Microsoft has acknowledged the issue and released an out-of-band update in December 2025 to resolve it. However, some users may still be hesitant to install this patch until the known problems are fully addressed.
