an "Explorer" style dialog window instead of classic dialog in Windows using folder.selectDialog()?

This is what I use, a cross-platform method that runs a PowerShell script to access the more modern(ish) folder picker dialog. Credit for this method is in the commented URL in the script.

// Better Windows folder picker via an elaborate powershell script
function betterFolderPicker(pickerTitle, defaultFolder)
{
	function powerShellCall(commandString)
	{
		return system.callSystem('cmd.exe /c powershell.exe -c "' + commandString +'"');
	}
	var folderForTempFiles = Folder.temp.fsName;
	//create a new textfile for writing the folder path from PowerShell
	var scratchFileName = "/ExtendscriptFolderPickerTempFile.txt";
	var scratchFile = new File(folderForTempFiles + scratchFileName);
	var chosenFolder = null;
	var chosenPath = null;

	if($.os.match(/Windows/) != null)
	{
