Summary:
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.
Details:
What and Why
The June 2026 Windows security update will be released as a hotpatch baseline update rather than a standard hotpatch update. This baseline refresh is required periodically to maintain the trusted foundation that enables future hotpatch updates to install without requiring device restarts.
