Changes

 * OS Loader has been updated to 4.01. However, it only shows this number when it displays that the user can press the spacebar to invoke the "Hardware Profile" menu. On the page where the user can select the OS, it still shows version 4.00. This is also the case for all subsequent updates of Windows NT 4.0.
 * The file copy dialog has been updated. This can be easily seen when installing applications such as Internet Explorer 3.
