Microsoft plans to release Windows 11 version 26H1 this spring. This update will support only devices equipped with the latest Qualcomm Snapdragon X2 ARM processors. Several hardware manufacturers have already confirmed the release.
ASUS, for instance, announced that its ZenBook A14 and A16 laptops featuring Snapdragon X2 chips will ship with Windows 11 version 26H1 pre-installed. In contrast, the ZenBook S14 and S16 models powered by Intel and AMD processors will include Windows 11 version 25H2 instead.

Windows 11 version 26H1: Some Details
Version 26H1 builds upon an updated foundation codenamed Bromine. This platform introduces performance and stability improvements absent in version 25H2. Additionally, the release includes optimizations specially made for Snapdragon X2 chips.
Despite differences in underlying architecture, both versions 25H2 and 26H1 will offer identical feature sets. As a result, most users will not find drastic differences between the two releases. Microsoft continues to develop new features on the 25H2 platform, and most of them will most likely appear in version 26H1.
Windows 11 version 26H1 will likely remain exclusive to new Snapdragon X2 devices. Users of other systems will receive the standard feature update, version 26H2, scheduled for release in the fall.
