Microsoft Fixes Startup Bug Affecting Windows Server 2022
Microsoft's latest update fixes an issue in Windows Server 2022 that causes startup failures.
Key Takeaways:
- Microsoft released an update to resolve an issue causing Windows Server 2022 systems with two or more NUMA nodes to fail to start properly.
- NUMA is a memory design that boosts performance by prioritizing local memory access for processors.
- The update includes the servicing stack update (KB5050117) to enhance the reliability of the update installation process on Windows Server 2022.
Microsoft has issued a fix to address a bug impacting Windows Server 2022 machines with two or more NUMA nodes. The company has acknowledged that this issue previously caused these systems to fail during startup.
What is NUMA?
Non-Uniform Memory Access (NUMA) is a memory architecture used in multiprocessor systems where the time it takes for a processor to access memory varies based on the memory’s location relative to the processor. In NUMA, each processor has its local memory that is accessible more quickly than memory shared with other processors or located far away.
This design enhances performance in high-performance computing environments by reducing memory access delays. NUMA is widely implemented in Windows Servers that have multiple physical CPUs or multi-core processors.
“Some servers that have two or more NUMA nodes fail to start up,” Microsoft explained in a support document. “If you installed earlier updates, only the new updates contained in this package will be downloaded and installed on your device.”
Microsoft has also released the servicing stack update (KB5050117) for Windows Server 2022. This release brings quality improvements to the servicing stack, which is a critical component in Windows responsible for installing updates.
In related news, Microsoft has resolved a bug that caused Microsoft 365 Apps to crash on Windows Server 2019 and 2016. The issue stemmed from a recent Office update that integrated the React Native framework. Microsoft has provided a workaround for users who haven’t yet received the automatic update.
