function Microwin-RemoveFeatures() {
    <#
        .SYNOPSIS
            Removes certain features from ISO image

        .PARAMETER UseCmdlets
            Determines whether or not to use the DISM cmdlets for processing.
            - If true, DISM cmdlets will be used
            - If false, calls to the DISM executable will be made whilst selecting bits and pieces from the output as a string (that was how MicroWin worked before
              the DISM conversion to cmdlets)

        .EXAMPLE
            Microwin-RemoveFeatures -UseCmdlets $true
    #>
    param (
        [Parameter(Mandatory = $true, Position = 0)] [bool]$UseCmdlets
