    .SYNOPSIS
        Creates a bootable VHD(X) based on Windows 7,8, 10, 11 or Windows Server 2012, 2012R2, 2016, 2019, 2022 installation media.

    .DESCRIPTION
        Creates a bootable VHD(X) based on Windows 7,8, 10, 11 or Windows Server 2012, 2012R2, 2016, 2019, 2022 installation media.

    .PARAMETER SourcePath
        The complete path to the WIM or ISO file that will be converted to a Virtual Hard Disk.
        The ISO file must be valid Windows installation media to be recognized successfully.

    .PARAMETER CacheSource
        If the source WIM/ISO was copied locally, we delete it by default.
        Pass $true to cache the source image from the temp directory.

    .PARAMETER VHDPath
        The name and path of the Virtual Hard Disk to create.
        Omitting this parameter will create the Virtual Hard Disk is the current directory, (or,
        if specified by the -WorkingDirectory parameter, the working directory) and will automatically
        name the file in the following format:

        <build>.<revision>.<architecture>.<branch>.<timestamp>_<skufamily>_<sku>_<language>.<extension>
        i.e.:
        9200.0.amd64fre.winmain_win8rtm.120725-1247_client_professional_en-us.vhd(x)

    .PARAMETER WorkingDirectory
        Specifies the directory where the VHD(X) file should be generated.
        If specified along with -VHDPath, the -WorkingDirectory value is ignored.
        The default value is the current directory ($pwd).

    .PARAMETER TempDirectory
        Specifies the directory where the logs and ISO files should be placed.
        The default value is the temp directory ($env:Temp).

    .PARAMETER SizeBytes
        The size of the Virtual Hard Disk to create.
        For fixed disks, the VHD(X) file will be allocated all of this space immediately.
        For dynamic disks, this will be the maximum size that the VHD(X) can grow to.
        The default value is 40GB.

    .PARAMETER VHDFormat
        Specifies whether to create a VHD or VHDX formatted Virtual Hard Disk.
        The default is AUTO, which will create a VHD if using the BIOS disk layout or
        VHDX if using UEFI or WindowsToGo layouts.

    .PARAMETER IsFixed
        Specifies to create a fixed (fully allocated) VHD(X) instead of dynamic (quick allocation of space) VHD(X).

    .PARAMETER DiskLayout
        Specifies whether to build the image for BIOS (MBR), UEFI (GPT), or WindowsToGo (MBR).
        Generation 1 VMs require BIOS (MBR) images.  Generation 2 VMs require UEFI (GPT) images.
        Windows To Go images will boot in UEFI or BIOS but are not technically supported (upgrade
        doesn't work)

    .PARAMETER UnattendPath
        The complete path to an unattend.xml file that can be injected into the VHD(X).

    .PARAMETER Edition
        The name or image index of the image to apply from the ESD/WIM. If omitted and more than one image is available, all images are listed.

    .PARAMETER Passthru
        Specifies that the full path to the VHD(X) that is created should be
        returned on the pipeline.

    .PARAMETER BCDBoot
        By default, the version of BCDBOOT.EXE that is present in \Windows\System32
        is used by Convert-WindowsImage.  If you need to specify an alternate version,
        use this parameter to do so.

    .PARAMETER MergeFolder
        Specifies additional MergeFolder path to be added to the root of the VHD(X)

    .PARAMETER BCDinVHD
        Specifies the purpose of the VHD(x). Use NativeBoot to skip cration of BCD store
        inside the VHD(x). Use VirtualMachine (or do not specify this option) to ensure
        the BCD store is created inside the VHD(x).

    .PARAMETER Driver
        Full path to driver(s) (.inf files) to inject to the OS inside the VHD(x).

    .PARAMETER ExpandOnNativeBoot
        Specifies whether to expand the VHD(x) to its maximum suze upon native boot.
        The default is True. Set to False to disable expansion.

    .PARAMETER RemoteDesktopEnable
        Enable Remote Desktop to connect to the OS inside the VHD(x) upon provisioning.
        Does not include Windows Firewall rules (firewall exceptions). The default is False.

    .PARAMETER Feature
        Enables specified Windows Feature(s). Note that you need to specify the Internal names
        understood by DISM and DISM CMDLets (e.g. NetFx3) instead of the "Friendly" names
        from Server Manager CMDLets (e.g. NET-Framework-Core).

    .PARAMETER Package
        Injects specified Windows Package(s). Accepts path to either a directory or individual
        CAB or MSU file.

    .PARAMETER ShowUI
        Specifies that the Graphical User Interface should be displayed.

    .PARAMETER EnableDebugger
        Configures kernel debugging for the VHD(X) being created.
        EnableDebugger takes a single argument which specifies the debugging transport to use.
        Valid transports are: None, Serial, 1394, USB, Network, Local.

        Depending on the type of transport selected, additional configuration parameters will become
        available.

        Serial:
            -ComPort   - The COM port number to use while communicating with the debugger.
                         The default value is 1 (indicating COM1).
            -BaudRate  - The baud rate (in bps) to use while communicating with the debugger.
                         The default value is 115200, valid values are:
                         9600, 19200, 38400, 56700, 115200

        1394:
            -Channel   - The 1394 channel used to communicate with the debugger.
                         The default value is 10.

        USB:
            -Target    - The target name used for USB debugging.
                         The default value is "debugging".

        Network:
            -IPAddress - The IP address of the debugging host computer.
            -Port      - The port on which to connect to the debugging host.
                         The default value is 50000, with a minimum value of 49152.
            -Key       - The key used to encrypt the connection.  Only [0-9] and [a-z] are allowed.
            -nodhcp    - Prevents the use of DHCP to obtain the target IP address.
            -newkey    - Specifies that a new encryption key should be generated for the connection.

    .PARAMETER DismPath
        Full Path to an alternative version of the Dism.exe tool. The default is the current OS version.

    .PARAMETER ApplyEA
        Specifies that any EAs captured in the WIM should be applied to the VHD.
        The default is False.

    .EXAMPLE
        Convert-WindowsImage -SourcePath D:\foo\install.wim -Edition Professional -WorkingDirectory D:\foo

        This command will create a 40GB dynamically expanding VHD in the D:\foo folder.
        The VHD will be based on the Professional edition from D:\foo\install.wim,
        and will be named automatically.

    .EXAMPLE
        Convert-WindowsImage -SourcePath D:\foo\Win7SP1.iso -Edition Ultimate -VHDPath D:\foo\Win7_Ultimate_SP1.vhd

        This command will parse the ISO file D:\foo\Win7SP1.iso and try to locate
        \sources\install.wim.  If that file is found, it will be used to create a
        dynamically-expanding 40GB VHD containing the Ultimate SKU, and will be
        named D:\foo\Win7_Ultimate_SP1.vhd

    .EXAMPLE
        Convert-WindowsImage -SourcePath "D:\foo\WindowsServer2019.iso" -VHDFormat "VHDX" -Edition "Windows Server 2019 Standard" -SizeBytes 30GB -isFixed -DiskLayout "UEFI" -VHDPath "D:\foo\WindowsServer2019.vhdx"

        This command will create a fixed size VHDX for Windows Server with the Edition set to Standard. It will use modern UEFI layout for the disk.

    .EXAMPLE
        Convert-WindowsImage -SourcePath D:\foo\install.wim -Edition Professional -EnableDebugger Serial -ComPort 2 -BaudRate 38400

        This command will create a VHD from D:\foo\install.wim of the Professional SKU.
        Serial debugging will be enabled in the VHD via COM2 at a baud rate of 38400bps.

            Functions to mount and dismount registry hives.
            These hives will automatically be accessible via the HKLM:\ registry PSDrive.

            It should be noted that I have more confidence in using the RegLoadKey and
            RegUnloadKey Win32 APIs than I do using REG.EXE - it just seems like we should
            do things ourselves if we can, instead of using yet another binary.

            Consider this a TODO for future versions.
