From 2026, Microsoft will make hotpatch security updates the default for eligible Windows devices managed via Intune or the Microsoft Graph API, starting with the May security cycle.
For years, administrators have endured the familiar routine of installing updates, rebooting systems, and hoping nothing breaks—a process often known as ‘patch-and-pray’. Hotpatching offers a less disruptive approach by applying critical fixes directly to running systems, eliminating the need for scheduled restarts. It’s akin to making targeted repairs to the operating system, rather than overhauling it each month.
The key benefits for IT include reduced downtime, improved user satisfaction, and fewer calls to the helpdesk. Security is strengthened by closing vulnerabilities as soon as patches are released, rather than waiting for maintenance windows. Operational issues caused by missed updates or machines refusing to reboot become far less of a problem.
However, not all Windows devices will benefit right away. Hotpatching is restricted primarily to systems managed via Intune or the Graph API, making it most relevant for enterprises and educational institutions. Small and medium businesses relying on legacy management tools should review their options and assess whether an upgrade might be necessary.
While the change marks significant progress, there are some limitations. Hotpatching is most effective for certain update types and may still occasionally require a reboot in specific scenarios. IT teams should expect to update their patch management processes, adjust policies, and conduct thorough testing as part of their preparations.
