Microsoft Confirms Arrival of Windows 11 Version 26H2

Microsoft has confirmed the arrival of Windows 11 version 26H2, the usual annual update of the operating system expected in the second half of 2026. The news comes with a precise condition: not all PCs will be able to install it, and the exclusion affects some of the more recent devices.

The new version is based on the same platform as Windows 11 25H2 and 24H2, sharing the same code base, security and quality updates, and the same compatibility validation with both. For those already using 24H2 or 25H2, the transition to 26H2 should therefore occur without the typical headaches of a traditional feature update, as what works today will continue to work after the update.

Microsoft describes the operation as the continuation of a more predictable and efficient maintenance model, designed to reduce disruptions and help organizations stay updated without having to plan a major migration project each year.

Windows 11 26H2: A Lightweight Update, No New Requirements

The distribution occurs through an Enablement Package, the same mechanism already used for the transition from 24H2 to 25H2. The operating system already contains most of the 26H2 code, simply inactive. The update only activates features via some internal flags, without downloading a complete image or migrating components. In practice, the process requires just one restart, with times significantly shorter compared to major updates from the past. Microsoft does not introduce new hardware requirements; those already compliant with Windows 11 24H2 or 25H2 will not face any new technical hurdles to install 26H2.

The release also triggers a new support cycle. The Home, Pro, Pro Education, and Pro for Workstations editions will receive updates for 24 months from general availability, while the Enterprise, Education, IoT Enterprise, and Enterprise Multi-session editions extend to 36 months. For IT departments, Microsoft recommends starting tests now via the Insider Experimental channel, then managing the rollout on a large scale with tools like Intune, Windows Autopatch, and WSUS.

The Exclusion: Who is Left Out

The exclusion concerns devices with Windows 11 26H1, the branch designed exclusively for PCs with Qualcomm Snapdragon X2 and NVIDIA RTX Spark chips. Those who own one of these systems will not see the upgrade offer to 26H2 this fall.

The reason is technical, not commercial. Windows 11 26H1 relies on a branch of the platform that is more recent than the one shared by 24H2, 25H2, and 26H2, making it, at a base level, even more up to date than 26H2 itself. Microsoft has confirmed that these devices will still receive a dedicated upgrade path to a subsequent version of the operating system, although no precise date has been indicated yet.

Regarding the general availability of 26H2, Microsoft has not set a specific release date. The history of previous versions, which have almost always arrived between late September and October, suggests a similar window for fall 2026, with an installation expected to be among the fastest and least painful in recent years.
