What’s New in KB5051987
This month's security update is built upon the improvements introduced with KB5050094 released just a couple of weeks earlier on January 28, 2025. The primary focus of KB5051987 is on bolstering the internal security of Windows 11 and making miscellaneous enhancements to the operating system’s core functionality. While no dramatic new features were rolled out, the update cements a series of critical security fixes that help keep your Windows environment robust against emerging threats.Key Improvements:
- Enhanced Security Fixes: The update addresses several security vulnerabilities, thereby strengthening the integrity of Windows 11.
- Servicing Stack Update Included: Integrated with the update is the Windows 11 servicing stack update KB5052085 (version 26100.3189), which streamlines and stabilizes the update process. Servicing stack updates (SSUs) are foundational, ensuring your system can reliably download and install subsequent patches.
- Incremental Update Delivery: For users who’ve installed previous updates, only the new additions contained within KB5051987 will be downloaded, thus simplifying the update process.
Known Issues and Workarounds
Despite the update’s critical importance, Microsoft has flagged a few known issues that deserve extra attention:Roblox on ARM Devices
- Issue: Players on ARM-based devices are currently unable to download and play Roblox via the Microsoft Store.
- Workaround: ARM device users can sidestep the store by downloading Roblox directly from the official website (Roblox). This workaround ensures gamers can continue enjoying their favorite title without disruption.
Open Secure Shell (OpenSSH) Service Problems
- Issue: Some customers reported that the OpenSSH service fails to start after installing the October 2024 security update. This issue disrupts SSH connections and appears without any detailed logging, forcing manual intervention.
- Temporary Fix: Users can update the permissions on the directories
C:\ProgramData\sshandC:\ProgramData\ssh\logsusing PowerShell. The steps include running elevated PowerShell commands to grant full control for SYSTEM and the Administrators group, while offering authenticated users read-only access. Detailed commands to modify the permissions are provided in the update documentation. - Note: This issue affects enterprise environments, IoT devices, and educational institutions predominantly. Microsoft is actively investigating whether consumer editions (Home or Pro) are impacted.
Citrix Compatibility
- Issue: Devices running the Citrix Session Recording Agent (SRA) version 2411 (released in December 2024) might experience update failures. When reinstalling, a rollback error message—typically stating “Something didn’t go as planned. No need to worry – undoing changes”—may appear.
