    Build 28120.2315 is part of the Windows 11 Insider Experimental (26H1) channel rollout. Experimental (26H1) builds are pre-release, can be unstable, and are delivered via Windows Update to devices enrolled in that channel.

    Key points for this channel:

    • Builds may ship with limited documentation and can change, be removed, or never ship broadly.
    • Features are often controlled by Controlled Feature Rollout (CFR) and may appear only for a subset of devices at first.
    • A desktop watermark in the lower-right corner is expected for these Insider builds.
    • For new features, use the Feature flags page under Settings > Windows Update > Windows Insider Program to see what can be toggled on when available.

    If a device is already in the Experimental (26H1) / former Canary 28000-series track, Windows Update will offer the build automatically once it is staged for that device.
