Overview
- Multiple reports confirmed on June 23 that Microsoft began automatically installing Windows 11 version 25H2 on compatible Home and Pro PCs that are not managed by corporate IT.
- The update is very small—about 200 kilobytes—installs in minutes with a short restart, and is delivered as a quick activation-style package rather than a full feature download.
- Microsoft says 25H2 shares the same code base as the announced 26H2, so the next major release can be turned on later by a tiny enablement package and Windows Insiders can already test 26H2 preview builds.
- 25H2 focuses on security hardening, including AI-assisted code checks and removal of legacy tools such as PowerShell 2.0 and WMIC, and Microsoft is using an intelligent, machine‑learning rollout to sequence installs while exempting IT-managed enterprise devices.
- The move continues Microsoft’s shift away from disruptive full-version upgrades toward incremental enablement updates, and it extends support for many consumer machines while removing the option for users to decline the 25H2 installation.
