SHA-256 reference is outdated

Hello Microsoft Support,

I downloaded the Windows 11 IoT Enterprise LTSC 2024 Evaluation x64 ISO directly from Microsoft's official Evaluation Center.

The downloaded file's SHA-256 is:

2CEE70BD183DF42B92A2E0DA08CC2BB7A2A9CE3A3841955A012C0F77AEB3CB29

However, Microsoft's official verification PDF lists:

8ABF91C9CD408368DC73AAB3425D5E3C02DAE74900742072EB5C750FC637C195

Can Microsoft confirm whether the downloaded ISO is authentic and whether the published SHA-256 reference is outdated?

I want to verify the installation media before using it in a Hyper-V virtual machine.

Thank you.

    Hello Microsoft Support Team,

    I am requesting official verification of a Windows 11 IoT Enterprise LTSC 2024 Evaluation ISO downloaded directly from Microsoft's Evaluation Center.

    Downloaded ISO details:

    • Edition: Windows 11 IoT Enterprise LTSC 2024 Evaluation

    Architecture: x64 / AMD64

    Filename: 26100.1742.240906-0331.ge_release_svc_refresh_CLIENT_IOT_LTSC_EVAL_x64FRE_en-us.iso

    File size: 5,060,020,224 bytes

    Source: Official Microsoft Evaluation Center

    SHA-256 calculated from downloaded ISO:

    2CEE70BD183DF42B92A2E0DA08CC2BB7A2A9CE3A3841955A012C0F77AEB3CB29

    SHA-256 listed in Microsoft's official verification PDF for x64:

    8ABF91C9CD408368DC73AAB3425D5E3C02DAE74900742072EB5C750FC637C195

    The downloaded file matches the size provided by Microsoft's download server, but its SHA-256 differs from the official verification document.

    I understand that other users have reported similar discrepancies.

    Could Microsoft please confirm:

    Is the downloaded ISO with SHA-256 2CEE70BD183DF42B92A2E0DA08CC2BB7A2A9CE3A3841955A012C0F77AEB3CB29 an authentic Microsoft release?

    Does the published x64 SHA-256 reference correspond to a different or earlier build?

    Is there an updated official checksum or verification document for the ISO currently distributed through the Evaluation Center?

    I intend to use this ISO in an isolated Hyper-V virtual machine for software evaluation and would like to verify its authenticity before installation.

    Thank you for your assistance.Hello Microsoft Support Team,

    The downloaded x64 ISO matches Microsoft’s currently published SHA-256 value; the apparent discrepancy comes from comparing it with the ARM64 value, not from an outdated reference.

    Published hashes

    Microsoft’s official hash document lists these architecture-specific values ^1^:

    • x64 / AMD64 2CEE70BD183DF42B92A2E0DA08CC2BB7A2A9CE3A3841955A012C0F77AEB3CB29
    • ARM64 8ABF91C9CD408368DC73AAB3425D5E3C02DAE74900742072EB5C750FC637C195

    Your calculated value is therefore the correct published value for the Windows 11 IoT Enterprise LTSC 2024 Evaluation x64 ISO. The Evaluation Center provides separate x64/AMD64 and ARM64 downloads and links to this verification document ^2^.

    Because your SHA-256 result matches the official x64 value, Microsoft’s verification guidance indicates that the file has not been corrupted, tampered with, or altered from the published original. It is suitable to use as the x64 installation media for your Hyper-V evaluation VM.

    For reproducibility, the documented Windows command is:

    Get-FileHash -Path "C:\Path\Windows11IoTEnterpriseLTSC2024.iso" `
    -Algorithm SHA256

    Get-FileHash uses SHA-256 by default, although specifying the algorithm explicitly avoids ambiguity ^3^.
