Microsoft has extended Windows Server 2022 Datacenter: Azure Edition hotpatching through October 2027, allowing enrolled systems to receive monthly security updates without rebooting by patching running processes; non-hotpatch updates still require restarts. The extended support end date for Windows Server 2022 editions remains 2031 for broader SKUs.
Microsoft released an out-of-band hotpatch (KB5084597) to fix RRAS remote-code-execution vulnerabilities on Windows 11 25H2/24H2 and Enterprise LTSC 2024. The fixes (CVE-2026-25172, -25173, -26111) were added to an in-memory patch that also updates on-disk files, enabling the patch to apply without reboot for devices enrolled in the hotpatch program and Windows Autopatch. The update is a re-release of earlier hotfixes to ensure comprehensive coverage alongside the March 2026 Patch Tuesday fixes; it targets enterprise systems that cannot reboot easily and will install automatically without restart when available.
