Windows 11 version 25H2 is available from September 30, 2025. Upgrading during October (a baseline month) keeps devices eligible for hotpatch updates; upgrading outside baseline months pauses hotpatching until the next baseline. Organizations should schedule upgrades accordingly to maintain hotpatch continuity.
