Microsoft announced that Windows 11 26H1 will be supported for consumers until March 2028, with rollout starting for PCs with eligible CPUs, specifically the Snapdragon X2 family, which includes Snapdragon X2 Plus, Snapdragon X2 Elite, and Snapdragon X2 Elite Extreme. The official launch occurred on February 10, 2026, alongside its first cumulative update. Users with first-generation Snapdragon Copilot+ PCs cannot upgrade to this version. Windows 11 26H1 is described as a "hardware-optimized release" aimed at enhancing performance and efficiency for Arm-based chips, though it does not promise significant enhancements over version 25H2 or the upcoming 26H2. Enterprise and Education editions will be supported until March 13, 2029, while Home and Pro editions will be supported until March 14, 2028. Windows 11 SE is not supported in 26H1. A new release, Windows 11 26H2, is expected to be available for all users, including those with first-generation Arm-based PCs, and will be the recommended update for broader deployment. Upgrades from version 25H1 to 26H1 are not possible, and all upgrade paths are currently closed, with plans to transition to version 27H2 in the latter half of 2027.
