hotpatching

About this tag
Hotpatching is a Windows Server and Windows 11 servicing feature that allows security updates to install without requiring a system reboot, reducing downtime for critical systems. On WindowsForum.com, discussions center on Microsoft's extension of hotpatching support for Windows Server 2022 Datacenter: Azure Edition through October 2027, providing an extra year of reboot-light updates beyond the operating system's mainstream support end. The feature is edition-specific and not available for standard on-premises Server 2022 deployments. Threads also cover operational realities, such as the June 2026 hotpatch break where a publicly disclosed vulnerability forced a restart-required baseline update, and the integration of hotpatching with Autopatch and Intune management. The tag reflects both the strategic value of reduced-reboot patching and its limitations within Microsoft's cloud-focused servicing roadmap.
