There has been understandable confusion around the Windows 11 version numbers appearing in 2026. Microsoft’s official release information states that Windows 11 version 26H1 is scoped to support new devices that came to market in early 2026.
Importantly, Microsoft says 26H1 is not designed as a feature update for existing devices and is not offered as an in-place update from Windows 11 24H2 or 25H2.
What this means
If your existing business PC is on a supported version of Windows 11, there is no need to hunt for a 26H1 upgrade. Continue using Windows Update and your normal managed update process.
