Microsoft has issued unscheduled updates for both Windows Server 2022 and Windows 10 to address specific issues arising from previous updates. These patches are necessary for certain systems, particularly those utilizing Hyper-V and Bitlocker.
Windows Server 2022 Update
Over the weekend, Microsoft released an update for Windows Server 2022 that addresses problems with Hyper-V. According to the Windows Message Center, this issue primarily affects Azure Confidential VMs, which may experience unexpected stops or restarts. The update, labeled KB5061906, upgrades the operating system to version 20348.3695 and is categorized as a non-security update. Users not experiencing these issues are not required to install it.
Windows 10 Update
Earlier in the week, another out-of-cycle update was released for Windows 10, specifically targeting problems with certain Intel vPro processors using Trusted Execution Technology (TXT) and Bitlocker. According to the Windows Message Center, the May security updates may sometimes terminate the “lsass.exe” process incorrectly, which initiates a forced recovery key prompt for Bitlocker encryption.
This update is documented in KB5061768 and applies to Windows 10 versions 21H2 and 22H2, including Windows 10 Enterprise LTSC 2021 and Windows 10 IoT Enterprise LTSC 2021. Like the update for Windows Server, this fix is only available via the Windows Update Catalog, and Microsoft recommends it for users impacted by the previously mentioned problem.
Conclusion
These updates reflect Microsoft’s ongoing efforts to ensure system stability and security, especially in environments using advanced features like Hyper-V and Bitlocker. Unplanned updates have become more common at Microsoft, aiming to promptly mitigate significant issues and enhance user experience.
