function Invoke-WinUtilISOScript {
<#
.SYNOPSIS
Applies the standard WinUtil modifications to a mounted Windows 11 install.wim image.
.DESCRIPTION
Removes bloatware AppX packages, Edge, OneDrive, applies privacy/telemetry
registry tweaks, disables sponsored-app delivery, bypasses hardware checks,
copies autounattend.xml for local-account OOBE, and deletes unwanted
scheduled-task definition files — all against an already-mounted WIM image.
Mounting and dismounting the WIM is the responsibility of the caller
(e.g. Invoke-WinUtilISOModify).
.PARAMETER ScratchDir
Full path to the directory where the Windows image is currently mounted
(the "scratchdir"). Example: C:\Temp\WinUtil_Win11ISO_20260222\wim_mount
.PARAMETER Log
Optional ScriptBlock used for progress/status logging.
Receives a single [string] message argument.
Defaults to Write-Output when not supplied.
.EXAMPLE
Invoke-WinUtilISOScript -ScratchDir "C:\Temp\wim_mount"
Invoke-WinUtilISOScript -ScratchDir $mountDir -Log { param($m) Write-Host $m }
