This page describes Windows 11, version 26H1, a targeted release designed for new devices launching in early 2026, specifically those with Qualcomm Snapdragon X2 Series processors. It is not available as an in-place update for existing devices running earlier versions. Organizations can confidently continue purchasing and deploying broadly released Windows 11 versions like 24H2 and 25H2 without changing their plans. Version 26H1 is not a feature update for 25H2 and will not support updates to the next annual feature release in late 2026 due to different core architecture. Devices running 26H1 will receive regular monthly updates for security and quality.
