Microsoft is shifting the Windows 11 roadmap by dedicating the Windows 11 26H1 update exclusively to new and upcoming Arm-based processors such as the Snapdragon X2 Elite/Plus. This move represents a significant change in Windows 11 development and marks the first recent divergence in Windows deployment between hardware classes. As a result of this decision, mainstream x86-64 PCs and older Arm-based platforms will remain on Windows 11 25H2 for their feature update path instead of moving to 26H1.
According to the Windows IT Pro Blog, “Windows 11, version 26H1 is not a feature update for version 25H2,” which signals that a different Windows 11 version will serve as the next full feature update after 25H2. Microsoft is instead positioning 26H1 as a specialized branch focused on silicon enablement rather than broad new functionality. The release is tailored for Windows-on-Arm platforms, with an emphasis on ensuring compatibility, performance and stability for the latest Arm-based designs.
Microsoft is concentrating engineering resources on optimizing Windows 11 for platforms including Qualcomm’s Snapdragon X2 Elite processors and NVIDIA’s N1 and N1x SoCs. The company notes that new silicon requires detailed tuning, including specific power profiles and hardware optimizations, to extract maximum performance and deliver the best user experience. By placing these changes in a separate 26H1 branch, Microsoft aims to simplify servicing and updates while preventing custom power and performance configurations for Arm hardware from affecting or corrupting builds intended for non-Arm CPUs.
