  "description": "The June 2026 Windows security update will be a hotpatch baseline update requiring a device restart on hotpatch-enabled devices. This one-time restart maintains the foundation for future restart-free hotpatches, with the next expected in August 2026. Non-hotpatch devices are unaffected.",
