function Invoke-WinUtilISOScript {
    <#
    .SYNOPSIS
        Applies WinUtil modifications to a mounted Windows 11 install.wim image.

    .DESCRIPTION
        Removes AppX bloatware and OneDrive, optionally injects all drivers exported from
        the running system into install.wim and boot.wim (controlled by the
        -InjectCurrentSystemDrivers switch), applies offline registry tweaks (hardware
        bypass, privacy, OOBE, telemetry, update suppression), deletes CEIP/WU
        scheduled-task definition files, and optionally writes autounattend.xml to the ISO
        root and removes the support\ folder from the ISO contents directory.

        All setup scripts embedded in the autounattend.xml <Extensions><File> nodes are
        written directly into the WIM at their target paths under C:\Windows\Setup\Scripts\
        to ensure they survive Windows Setup stripping unrecognised-namespace XML elements
        from the Panther copy of the answer file.

        Mounting/dismounting the WIM is the caller's responsibility (e.g. Invoke-WinUtilISO).

    .PARAMETER ScratchDir
        Mandatory. Full path to the directory where the Windows image is currently mounted.

    .PARAMETER ISOContentsDir
        Optional. Root directory of the extracted ISO contents. When supplied,
        autounattend.xml is written here and the support\ folder is removed.

    .PARAMETER AutoUnattendXml
        Optional. Full XML content for autounattend.xml. If empty, the OOBE bypass
        file is skipped and a warning is logged.

    .PARAMETER InjectCurrentSystemDrivers
        Optional. When $true, exports all drivers from the running system and injects
        them into install.wim and boot.wim index 2 (Windows Setup PE).
        Defaults to $false.

    .PARAMETER Log
        Optional ScriptBlock for progress/status logging. Receives a single [string] argument.

    .EXAMPLE
        Invoke-WinUtilISOScript -ScratchDir "C:\Temp\wim_mount"

    .EXAMPLE
