  "textContent": "## What and why\n\nThe June 2026 Windows security update will be released as a **standard update** instead of a **hotpatch update**. As a result, hotpatch-enabled devices will require a restart to complete installation.\n\nThis change prioritizes security following public disclosure of a vulnerability outside coordinated disclosure best practices (CVE-2026-45585).\n\n## Rollout schedule\n\n  * **June 2026:** Standard update with restart required for hotpatch-enabled devices.\n  * **July 2026:** Planned baseline update month with restart required.\n  * **August 2026:** Next hotpatch update expected.\n\n\n\n## Impact on your organization\n\n  * Hotpatch-enabled devices will require a restart to complete installation of the June 2026 security update.\n  * Hotpatch-enabled devices will remain enrolled in hotpatch updates.\n  * No change for devices not using hotpatch updates (standard updates already require restart).\n\n\n\n## Action required / recommendations\n\nNo additional configuration is required to stay enrolled in hotpatch updates.\n\n## Compliance considerations\n\nNo compliance action is required. Update installation and restart behavior will be reflected in update history and compliance reports as usual.\n\n## Additional information\n\nYou can track the hotpatch update calendars on the Windows release health site for both Windows 11 and Windows Servers.",
