"Windows 11 26H1" is a special version of Windows exclusively for new Arm PCs

Since its release in the fall of 2021, Microsoft's Windows 11 has received an "annual feature update" in the second half of every year. These feature updates sometimes include new Windows features and other changes that are too large to roll out in a typical monthly Windows Update, and users need to upgrade to new ones to keep getting security patches and other features. The currently supported versions are Windows 11 24H2 and 25H2, released in the fall of 2024 and 2025, respectively.
