    Build 26220.8491 for the Windows 11 Insider Beta Channel is not listed in the provided context. The latest Beta build information available here is for build 26220.8474, released on May 15, 2026. That build:

    • Is based on Windows 11, version 25H2 via an enablement package (KB5054156).
    • Includes improvements such as:
      • Reliability improvements for Simple Service Discovery Protocol (SSDP) notifications.
      • Improved reliability when running dism /online /cleanup-image /restorehealth.
      • A fix where File Explorer’s Properties did not invoke correctly for Recycle Bin and some other scenarios.
      • Fluid Dictation for Spanish and French in voice access and Voice typing (Win+H), powered by on-device small language models.
    • Has a known issue where “Reset this PC” can get stuck; the workaround is to use the cloud download option (Cloud PBR).
    • Shows the usual Insider desktop watermark and carries the standard reminder that features may be experimental and not fully localized.
