Microsoft has made hotpatch updates available for business customers using Windows 11 Enterprise 24H2 on x64 systems, allowing seamless installation of security updates without device reboots. Hotpatching modifies in-memory code of active processes to deploy updates without interrupting user activities. Devices under a hotpatch-enabled quality update policy will receive updates quarterly, with no restarts required for eight months of the year. A Microsoft subscription is necessary to activate hotpatching, and devices must meet specific prerequisites, including an x64 CPU and enabled Virtualization-based Security. Hotpatch updates can be managed through Microsoft Intune, and devices on Windows 10 and versions 23H2 and lower will continue to receive standard updates. Microsoft initially introduced hotpatch support for Windows Server Azure Edition in February 2022 and has expanded testing to include Windows 11 24H2.
