Announcing new builds for 19 June 2026, version 26H2 for Experimental

Hello Windows Insiders,

We have new releases today with builds across Beta and Experimental, including Windows 11, version 26H2 for Experimental.

Windows 11, version 26H2

Windows 11, version 26H2 represents our yearly second half major update as part of our standard annual Windows 11 update cadence. As Windows 11, version 26H2 shares the same servicing branch as Windows 11, version 25H2, the update is implemented through an enablement package (eKB). This means your device will be updated to the next version through a single restart – providing a familiar, fast, and reliable update experience.

Devices already enrolled in the Experimental channel will begin seeing their versioning updated to version 26H2 under Settings > System > About (and winver). If you are in the Beta channel and would like to switch to the Experimental, you can easily do so under Settings > Windows Update > Windows Insider Program. Remember, you can easily switch back to Beta at any time, without having to do a full Windows reinstall.

Not currently enrolled in the Windows Insider Program and wanting to preview version 26H2? Register for WIP selecting the Dev channel, while it’s transitioning to Experimental. Once the transition is complete, the new channel name to preview version 26H2 will appear as Experimental.

For more information on Windows 11, version 26H2, especially for IT professionals, please see Get ready for Windows 11, version 26H2.

Note: Devices running Windows 11, version 26H1 will not be able to update to version 26H2. Instead, they’ll have a path to update to a future Windows release. This is because Windows 11, version 26H1 is based on a different Windows core than Windows 11, versions 24H2, 25H2, and 26H2. Here’s What to know about Windows 11, version 26H1.
