Improve compatibility with vanilla Windows platforms

* Add a notice about PowerShell 3.0 being required. * Enable script to run on platforms without Microsoft.mshtml assembly. * Add a -DisableFirstRunCustomize option to prevent an exception when the script is run on a platform where IE has never been launched. * Also display a notice about Microsoft anti bulk download
