Please provide your responses to the following three points.

１．Understanding of the Windows 11 25H2 delivery model

Based on the information provided in the article below, we understand the Windows 11 25H2 delivery model as follows.​https://news.mynavi.jp/techplus/article/20251001-3504095/

In a Windows 11 24H2 environment, it is possible to upgrade to Windows 11 25H2 in a short time by applying an Enablement Package.

On the other hand, if a device is not included in the Windows Update rollout, or if Windows 11 25H2 is installed using an ISO file or via the “Download Windows 11” website, the Enablement Package is not used.

In these cases, Windows 11 25H2 is applied as a standard feature update (full installation).

Is this understanding correct?

２．Confirmation of the deployment method for the planned verification scenarios

For the purpose of validating system behavior for Windows 11 25H2, we are planning to conduct verification using the following two scenarios.

①A clean installation of Windows 11 25H2. ②An upgrade from Windows 11 23H2 to Windows 11 25H2.

In these cases, both scenarios would be performed as standard installations (feature updates) using an ISO file. Is it correct to understand that the Enablement Package will not be used in either case?

３. Differences between deployment methods

Finally, we would like to confirm the following two deployment methods.

A Windows 11 25H2 environment installed or upgraded using a standard ISO-based installation.

A Windows 11 25H2 environment obtained by applying an Enablement Package to Windows 11 24H2.

Are there any differences in the final OS version or build configuration between these methods?

Are there any differences in system functionality or operational behavior?

If there is an official position or related documentation regarding this, we would appreciate your guidance.

    Hello 平澤輝仁 / HIRASAWA，TERUHITO,

    I found these two official sources that cover your questions:

    Your understanding is correct on all three points:

    • 24H2 > 25H2 via eKB — the enablement package only applies to 24H2 devices on Windows Update or WSUS, with KB5064081 as a prerequisite. ISO or clean install goes through the full feature update path instead.
    • 23H2 > 25H2 via ISO — the Windows Blog confirms: "devices on version 23H2 (and earlier) require a full operating system swap to update to 25H2." Full feature update, no eKB involved.
    • End result is identical — KB5054156 states: "versions 24H2 and 25H2 share a common core operating system with an identical set of system files." The path doesn't matter; you land on the same OS either way.

    I hope this helps!

    1. Your understanding of the Windows 11 25H2 delivery model is correct. The Enablement Package can be used for devices running Windows 11 24H2 to upgrade to 25H2 quickly. However, if a device is not part of the Windows Update rollout or if Windows 11 25H2 is installed via an ISO file or the "Download Windows 11" website, then the Enablement Package is not utilized, and the installation occurs as a standard feature update.
    2. For your planned verification scenarios, both a clean installation of Windows 11 25H2 and an upgrade from Windows 11 23H2 to Windows 11 25H2 using an ISO file will not use the Enablement Package. Therefore, your understanding that both scenarios will be standard installations (feature updates) is correct.
    3. Regarding the differences between the two deployment methods:
      • There should be no differences in the final OS version or build configuration between a standard ISO-based installation and an installation using the Enablement Package, as both will ultimately result in the same version of Windows 11 25H2.
      • However, there may be differences in the installation process and time taken, but in terms of system functionality and operational behavior, they should be consistent once the installation is complete.

    For official positions or related documentation, you may refer to Microsoft’s support resources for specific details on deployment methods and their implications.
