KB5071543: Overview with user sentiment and feedback

Overview

This security update for Windows Server 2016 and Windows 10 Enterprise LTSB 2016 includes fixes and improvements that are part of the November 11, 2025 update KB5068864 (OS Build 14393.8594). The key change documented in this update is related to the Invoke-WebRequest command in PowerShell 5.1, which now includes a confirmation prompt with a security warning about script execution risk. Users can choose to continue or cancel the request.

General Purpose

The main purpose of this update is to address security vulnerabilities and improve the overall security and stability of the operating system. Specifically, it includes changes to the PowerShell Invoke-WebRequest command to add a security prompt before executing scripts from web content. This helps mitigate the risk of script execution attacks. Beyond this, the update likely contains various other security fixes and quality improvements, though the details are not fully documented.

General Sentiment

The general sentiment around this update appears mixed. On one hand, the security improvements to PowerShell are likely welcomed by IT administrators and security-conscious users. However, the known issue with Message Queuing (MSMQ) functionality is concerning, as it can cause disruptions in enterprise environments that rely on MSMQ. The lack of a publicly available workaround for the MSMQ issue is also a point of frustration. Overall, the update seems to provide valuable security enhancements, but the MSMQ problems may outweigh the benefits for some organizations depending on the criticality of their MSMQ usage.

Known Issues

• After installing this update, users may face issues with the Message Queuing (MSMQ) functionality, including: - MSMQ queues becoming inactive - IIS sites failing with "Insufficient resources to perform operation" errors - Applications unable to write to queues - Errors creating message files in the C:WindowsSystem32msmqstorage folder- This issue is caused by changes to the MSMQ security model and NTFS permissions, which now require MSMQ users to have write access to the C:WindowsSystem32MSMQstorage folder, which is normally restricted to administrators.- This issue primarily affects enterprise or managed IT environments, and is unlikely to impact individual users on Windows Home or Pro editions.
