Hello Microsoft team,

I am looking for official, version-specific guidance for Windows ADK 10.1.26100.9457 (September 2026) on Windows 11 26H2 x64.

Objective

Acquire only the Microsoft ADK Deployment Tools packages required for Oscdimg, including their mandatory dependencies, without installing the ADK during the acquisition step.

The official ADK setup bootstrapper has already been acquired and verified using Microsoft's digital signature. No Deployment Tools packages have been acquired or installed.

Documentation reviewed

Install the Windows ADK offline

Windows ADK servicing

The documentation identifies OptionId.DeploymentTools for feature selection and /layout for downloading offline installation files.

However, the linked legacy installer command reference indicates that /layout cannot be combined with /features. It is unclear whether this restriction still applies to the September 2026 ADK release.

Questions

Does ADK 10.1.26100.9457 officially support downloading only OptionId.DeploymentTools and its required dependencies through a feature-restricted offline layout? If so, what is the supported command syntax?

If feature-restricted offline layout acquisition is unsupported, is there another Microsoft-supported method to acquire only the Deployment Tools packages without installing them or downloading the entire ADK payload?

Is an official package manifest available for this release identifying the required Deployment Tools package filenames, dependencies, versions, trusted download sources, sizes, and available integrity verification information?

Does ADK 10.1.26100.9457 require a separate servicing update? Specifically, is KB5101684, which appears associated with an older 10.1.26100.2454 branch, applicable to the September 2026 release, or are the relevant fixes already incorporated?

Expected result

We need a documented, minimal, verifiable acquisition procedure before separately authorizing installation.

No installer execution, package download, servicing operation, or installation has been performed as part of this inquiry.

Please provide official documentation or confirmation from the relevant Microsoft ADK product team where possible.

    Hello Wissam,

    Thank you for posting your question on the Microsoft Windows Forum!

    Thank you for the detailed and well-structured question. After reviewing the Microsoft documentation you referenced, I believe there is one important adjustment to make in the response.

    What Microsoft Documents

    The currently published ADK documentation clearly documents two separate operations:

    1. Offline acquisition (layout creation)

    adksetup.exe /quiet /layout <path>

    This downloads the files needed for offline installation and does not install the ADK. Microsoft documents this workflow in Install the Windows ADK offline. [microsoft.com]

    2. Feature selection during installation

    adksetup.exe /quiet /installpath <path> /features OptionId.DeploymentTools

    Microsoft documents OptionId.DeploymentTools as a supported installation feature selection. [microsoft.com]

    What Is Not Clearly Documented

    I was not able to find Microsoft documentation for ADK 10.1.26100.9457 that explicitly states that:

    adksetup.exe /layout <path> /features OptionId.DeploymentTools

    is a supported method of creating a feature-restricted offline layout.

    Likewise, I did not find documentation describing:

    • A package-only acquisition mechanism for Deployment Tools.
    • A Microsoft-published dependency manifest for Deployment Tools.
    • A supported method to download only the underlying Deployment Tools payload without creating an ADK layout.

    Because of that, I would avoid claiming that a feature-filtered layout is supported unless the ADK product team publishes release-specific guidance confirming it.

    About KB5101684

    Your question regarding KB5101684 is important.

    Microsoft's ADK servicing documentation identifies KB5101684 as an update associated with the earlier:

    ADK 10.1.26100.2454

    branch.

    I could not find documentation stating that KB5101684 is applicable to:

    ADK 10.1.26100.9457 (September 2026)

    Therefore, based on currently published documentation, I would not assume that KB5101684 should be applied to 10.1.26100.9457 unless Microsoft explicitly updates the servicing guidance to indicate that. The ADK servicing page remains the authoritative source for release-specific patches.

    My Assessment

    Based on currently published Microsoft documentation, the supported and documented workflow appears to be:

    1. Create a complete offline layout:
    adksetup.exe /quiet /layout C:\ADK\Layout
    1. After approval, install only Deployment Tools:
    adksetup.exe /quiet /installpath C:\ADK /features OptionId.DeploymentTools

    I have not found Microsoft documentation that establishes:

    • Feature-restricted layout acquisition.
    • Package-only Deployment Tools download.
    • A public package manifest containing dependency graphs, package hashes, or stable package URLs for Deployment Tools.

    Therefore, if your organization requires formal confirmation that no additional feature-filtered acquisition mechanism exists for ADK 10.1.26100.9457, that would likely require clarification from Microsoft Support or the ADK product team, as the public documentation currently describes only the full-layout workflow.

    The only Microsoft-documented acquisition procedure for ADK 10.1.26100.9457 is to download the complete offline layout first and select OptionId.DeploymentTools only during the later installation; Microsoft does not document a feature-restricted layout command or a package-only acquisition method.

    Supported offline procedure

    On an internet-connected acquisition system, run:

    New-Item -ItemType Directory -Path C:\ADK\Layout -Force

.\adksetup.exe /quiet /layout C:\ADK\Layout

    This downloads the offline ADK payload without installing it. Microsoft documents /layout for acquisition but applies /features only when running the downloaded setup on the offline destination system.^1^

    After the layout has passed your authorization process, install only Deployment Tools from the copied layout:

    C:\ADK\Layout\adksetup.exe /quiet `
    /installpath C:\ADK `
    /features OptionId.DeploymentTools

    The expected result is an installation containing Deployment Tools and dependencies selected by ADK Setup. Oscdimg is part of the Deployment Tools; a separate Windows PE add-on is not required merely to obtain Oscdimg. Windows PE is distributed separately when WinPE itself is needed.^2^

    Feature-restricted acquisition

    There is no published, supported syntax in the current ADK offline-install documentation equivalent to:

    adksetup.exe /layout <path> /features OptionId.DeploymentTools

    The documented command sequences keep these operations separate:

    • Acquisition: /quiet /layout <path>
    • Installation: /quiet /installpath <path> /features OptionId.DeploymentTools

    Consequently, combining /layout and /features should not be used as a controlled acquisition procedure unless the ADK product team supplies release-specific confirmation. Successful execution by the bootstrapper would not, by itself, establish that the combination is supported.

    The public documentation also does not identify another supported Microsoft tool or endpoint for downloading only the underlying Deployment Tools MSI/CAB packages without either:

    1. creating the complete ADK layout, or
    2. allowing ADK Setup to install the selected feature.

    Therefore, the stated requirement—minimal package acquisition without installation or downloading the full layout—does not currently have a documented public procedure.

    Package manifest and verification boundary

    The cited Microsoft documentation does not publish a release-specific external manifest for ADK 10.1.26100.9457 containing all of the following:

    • Deployment Tools package filenames;
    • dependency graph;
    • individual package versions and sizes;
    • stable package download URLs;
    • package hashes.

    Do not construct a package set by observing bootstrapper traffic or copying selected MSI/CAB files from another layout. That would rely on undocumented package composition and could omit installer-managed dependencies.

    For a controlled workflow, retain and verify the complete layout as one release artifact:

    1. Acquire it with the signed 10.1.26100.9457 bootstrapper.
    2. Preserve the complete directory tree.
    3. Record internal hashes after download, for example:
    Get-ChildItem C:\ADK\Layout -File -Recurse |
    Get-FileHash -Algorithm SHA256 |
    Sort-Object Path |
    Export-Csv C:\ADK\ADK-10.1.26100.9457-hashes.csv `
        -NoTypeInformation

    These are organization-generated inventory hashes, not Microsoft-published reference hashes. Microsoft’s current download page confirms that 10.1.26100.9457 replaces 10.1.26100.2454 and supports Windows 11 26H2.^2^

    KB5101684 and servicing

    Do not apply KB5101684 to ADK 10.1.26100.9457. Microsoft lists it specifically as:

    Windows ADK 10.1.26100.2454 Update KB5101684 for ADK 10.1.26100.2454 (December 2024)

    It is not listed as a patch for 10.1.26100.9457.^3^

    The 10.1.26100.9457 release notes already list the relevant Oscdimg boot-binary update, DISM security fixes, WSIM fix, OA3 changes, and App-V changes.^4^ Microsoft also states that only Deployment Tools changed among the 10.1.26100.x releases; their WinPE binaries remain version 10.1.26100.1.^5^

    Before a later installation is authorized, check the servicing page for a patch explicitly naming 10.1.26100.9457. ADK patches are applied to an existing installation, so they do not replace the initial offline-layout acquisition process.^3^

    For an authoritative statement that no unpublished package manifest or feature-filtered acquisition interface exists, this needs escalation to Microsoft Support or the ADK product team; the public documentation establishes only the full-layout workflow above.
