Builds 26100 and 26200 in the Release Preview (RP) Channel are part of the Windows 11, version 24H2 and 25H2 preview rollout. Release Preview provides pre‑release quality updates for upcoming Windows versions before they are generally available.
For Windows 11, version 24H2 (OS build 26100), Release Preview builds are tracked in Flight Hub. The table for version 24H2 shows multiple RP builds (for example, 26100.6713, 26100.7015, 26100.7296, 26100.7309, 26100.7701, 26100.7921, 26100.8106) that are delivered via Windows Update to devices enrolled in the Release Preview Channel.
Devices configured for Release Preview will see these builds “live” in Windows Update when Microsoft publishes them to RP. Installation is handled through the normal Windows Update flow; no additional action is required beyond being opted into the Release Preview Channel.
The screenshot text indicates the post is informational only and that any issues or questions about these builds should be raised in separate threads, which aligns with how official or moderator announcement posts are used to inform Windows Insider participants about new RP releases.
