Microsoft is exploring the implementation of hot-patching for Windows 11 24H2, which aims to streamline the update process without requiring mandatory restarts. This method will primarily apply to x86 versions of Windows and will be limited to monthly security updates. Users can expect fewer reboots, although a restart will still be necessary after every two hot-patch updates due to the release of four baseline updates that require a reboot. The benefits of hot-patching include reduced disruption, faster update processes, enhanced security, and simplified management with Azure Update Manager. Microsoft has previously used hot-patching successfully on Windows servers and Xbox consoles. No official timeline for the rollout of this feature has been announced.

Windows 11 is expected to introduce a 'hot-patching' feature with the 24H2 version, allowing certain cumulative updates to be applied without rebooting. A support article related to this feature was prematurely published and then removed by Microsoft, indicating ongoing development. The hot-patching process is designed to enable two consecutive cumulative updates to be installed without a reboot, followed by a third update that would require a restart. Microsoft may provide an update on this functionality by August 2024. Major annual updates will still necessitate a reboot. This feature aims to enhance user experience by allowing updates without disrupting workflows and reducing risks associated with rebooting during updates.
