Builds in the 26100 and 26200 ranges that are released to the Release Preview (RP) Channel appear in Windows Update the same way as other cumulative or preview updates.
For current Windows 11, version 24H2 Release Preview builds in the 26100 range, they are delivered as cumulative updates that include the latest servicing stack update (SSU). Examples:
- KB5046617 (OS Build 26100.2314)
- KB5048667 (OS Build 26100.2605)
- KB5053598 (OS Build 26100.3476)
These install automatically for devices configured for Release Preview via:
- Windows Update: downloaded and installed automatically, or
- Windows Update for Business: according to configured policies.
For preview (optional) RP updates, Windows Update shows them under Settings > Update & Security > Windows Update > Optional updates available, where they can be manually selected and installed.
Builds in the 26200 range mentioned in Insider discussions are also Insider preview builds. When they are targeted to Release Preview, they are obtained the same way—through Windows Update on devices enrolled in that channel—though specific KB numbers and availability depend on the flight schedule and are not detailed in the provided context.
All these updates combine SSU + LCU, so no separate SSU installation is required.
