Microsoft has pulled the January Windows Server cumulative updates after critical bugs caused domain controllers to reboot, Hyper-V to not work, and ReFS volume systems to become unavailable.
Tuesday, Microsoft released the January 2022 Patch Tuesday updates for Windows Server that includes numerous security updates and bug fixes.
These updates are KB5009624 for Windows Server 2012 R2, KB5009557 for Windows Server 2019, and KB5009555 for Windows Server 2022.
