Microsoft has released an update, KB5052819, to resolve a boot issue affecting Windows Server 2022 systems. The problem occurred specifically on systems using two or more Non-Uniform Memory Access (NUMA) nodes, a memory architecture commonly found in enterprise environments that use multi-core processors. This issue prevented these servers from starting correctly, disrupting operations and impacting usability. The update addresses the bug that was causing the servers to fail to boot properly and is available for download from the Microsoft Update Catalog.

In addition to the boot problem, Microsoft has also acknowledged issues with the SgrmBroker service after the January 2025 updates to both Windows 10 and Server 2022. This service, which is part of System Guard and monitors the integrity of the system, was failing to start. An out-of-band update has also been released to fix this issue, which was identified by administrators and users after the installation of the January 2025 security updates. The SgrmBroker service problem was also impacting systems running under Hyper-V.
