Details:

Windows 11, version 25H2 is now being offered to eligible devices via feature updates. For customers enrolled in hotpatch quality update policies, when the upgrade is taken can affect whether devices continue to receive hotpatch updates during the current hotpatch cycle. Devices that upgrade during a designated baseline release period (such as October) will remain eligible for hotpatching. Devices that upgrade during a non-baseline month (such as November) will temporarily stop receiving hotpatch updates and, until the next baseline release (e.g., January 2026), will instead receive standard security updates that require a restart.


When will this happen:
The Windows 11, version 25H2 upgrade will be offered starting September 30, 2025, with October 2025 designated as the baseline month for hotpatch eligibility. Organizations should plan their upgrade timing accordingly to maintain hotpatch continuity.

explanation for non-techies**

Windows 11, version 25H2, is now available for eligible devices, and if your organization uses hotpatch updates, the timing of this upgrade is crucial. Imagine your computer system as a car that needs regular maintenance to run smoothly. Hotpatch updates are like quick oil changes that keep everything running without needing to stop the car. However, if you upgrade your system at the wrong time, you might miss out on these quick updates and instead have to go through a more extensive service that requires you to park the car for a while.

In this context, October is like the designated time when the mechanic is ready to perform those quick oil changes without any downtime. If you upgrade during this period, your devices will continue to receive hotpatch updates. But if you miss this window and upgrade in November, for example, your devices will have to switch to standard updates, which are more like a full service requiring a temporary pause, until the next opportunity for hotpatch updates comes around in January 2026.

To keep everything running smoothly, it's important to plan your upgrades around these baseline months. Check your update schedule and make sure your devices are set to upgrade during these times. This way, you can ensure that your systems continue to receive the efficient hotpatch updates without interruption. For more detailed guidance, you can refer to the resources provided in the links.
