Windows 11 version names look like codes, but they follow a pattern: the year and the half (H1 or H2) when the feature update was released. Older guides that call 24H2 the latest are out of date. This guide explains each current version, who it is for, and the support dates Microsoft publishes.


| Version | Availability | Notes |
|---|---|---|
| 24H2 | 2024-10-01 | Home and Pro have reached the end of updates; Enterprise to 2027-10-12 |
| 25H2 | 2025-09-30 | Home and Pro updates until 2027-10-12 |
| 26H1 | Early 2026 devices | For new devices; not offered in place on 24H2 or 25H2 |
| 26H2 | Rolling out from September 2026 | Enablement package for 24H2 and 25H2 |

An enablement package is a small update that switches on features already delivered in earlier monthly updates. That is why the move to 26H2 from 24H2 or 25H2 needs only a small download and one restart. It also means the code base is the same, so these versions share most of their updates.


Not every Windows 10 PC can run Windows 11. Microsoft says to check the Windows 11 device specifications and warns that installing on an unsupported PC is not recommended and may result in compatibility issues, and that such a PC may not be entitled to updates.
