.SYNOPSIS
    Script to automatically download latest Admx files for several products.
 
.DESCRIPTION
    Script to automatically download latest Admx files for several products.
    Optionally copies the latest Admx files to a folder of your chosing, for example a Policy Store.
 
.PARAMETER Windows10Version
    The Windows 10 version to get the Admx files for. This value will be ignored if 'Windows 10' is
    not specified with -Include parameter.
    If the -Include parameter contains 'Windows 10', the latest Windows 10 version will be used.
    Defaults to "Windows11Version" if omitted.
 
 Note: Windows 11 23H2 policy definitions now supports Windows 10.
 
.PARAMETER Windows11Version
    The Windows 11 version to get the Admx files for. This value will be ignored if 'Windows 10' is
    not specified with -Include parameter.
    If omitted, defaults to latest version available .
 
.PARAMETER WorkingDirectory
    Optionally provide a Working Directory for the script.
    The script will store Admx files in a subdirectory called "admx".
    The script will store downloaded files in a subdirectory called "downloads".
    If omitted the script will treat the script's folder as the working directory.
 
.PARAMETER PolicyStore
    Optionally provide a Policy Store location to copy the Admx files to after processing.
 
.PARAMETER Languages
    Optionally provide an array of languages to process. Entries must be in 'xy-XY' format.
    If omitted the script will default to 'en-US'.
 
.PARAMETER UseProductFolders
    When specified the extracted Admx files are copied to their respective product folders in a subfolder of 'Admx' in the WorkingDirectory.
 
.PARAMETER CustomPolicyStore
    When specified processes a location for custom policy files. Can be UNC format or local folder.
    The script will expect to find .admx files in this location, and at least one language folder holding the .adml file(s).
    Versioning will be done based on the newest file found recursively in this location (any .admx or .adml).
    Note that if any file has changed the script will process all files found in location.
 
.PARAMETER Include
    Array containing Admx products to include when checking for updates.
    Defaults to "Windows 11", "Microsoft Edge", "Microsoft OneDrive", "Microsoft Office" if omitted.
 
.PARAMETER PreferLocalOneDrive
    Microsoft OneDrive Admx files are only available after installing OneDrive.
    If this script is running on a machine that has OneDrive installed, this switch will prevent automaticic uninstallation of OneDrive.
 
.EXAMPLE
    .\EvergreenAdmx.ps1 -Windows11Version "23H2" -PolicyStore "C:\Windows\SYSVOL\domain\Policies\PolicyDefinitions" -Languages @("en-US", "nl-NL") -UseProductFolders
    Get policy default set of products, storing results in product folders, for both en-us and nl-NL languages, and copies the files to the Policy store.
