Microsoft is developing a new version of Windows 11, codenamed Bromine (version 26H1), specifically designed for next-generation silicon chips like Qualcomm Snapdragon X2 and NVIDIA N1X. Here’s what we know so far:
* **Release Date:** Expected to ship in the first half of 2026 on devices with next-gen Arm silicon.
* **Availability:** Version 26H1 will only be available on PCs powered by these new Arm-based chips from Qualcomm and NVIDIA, not as a feature update for existing Windows 11 users (version 25H2).
* **New Features:** Although the exact features are unknown, it’s expected to have similar functionality to previous versions, with performance improvements due to the newer Bromine platform release.
* **Platform Updates:** The Bromine version includes necessary changes to support next-gen chips, making it a full OS upgrade. However, only Snapdragon X2 devices will be compatible at launch.
