General Sentiment

The general sentiment around this Windows Server 2008 R2 cumulative monthly update appears to be mixed. On the positive side, it addresses several known security vulnerabilities and includes quality-of-life improvements like the PowerShell Invoke-WebRequest security prompt. This helps improve the overall security posture of the aging Windows Server 2008 R2 platform.However, the update also introduces a known issue related to the Message Queuing (MSMQ) functionality. This issue can cause 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. While Microsoft has provided a resolution for this known issue in a subsequent out-of-band update, the presence of a disruptive bug dampens the overall sentiment. Customers running Windows Server 2008 R2 in enterprise or managed IT environments will need to carefully evaluate the update and potential impact before deployment.

Known Issues

• Message Queuing (MSMQ): After installing this update, users may face issues with the Message Queuing (MSMQ) functionality. This includes MSMQ queues becoming inactive, IIS sites failing with "Insufficient resources to perform operation" errors, and applications unable to write to queues. Errors such as "The message file 'C:WindowsSystem32msmqstorage*.mq' cannot be created" may also occur, despite sufficient disk space and memory being available. This is caused by recent changes to the MSMQ security model and NTFS permissions on the C:WindowsSystem32MSMQstorage folder, which now requires write access for MSMQ users (normally restricted to administrators). This issue primarily affects enterprise or managed IT environments, and not individual home or personal devices.
