Create a text document with extension .js
For example: itunes_reread.js

add the following code in the .js file, and save

var iTunesApp = WScript.CreateObject("iTunes.Application");
var tracks    = iTunesApp.LibraryPlaylist.Tracks;
var numTracks = tracks.Count;
var i;
for (i = 1; i <= numTracks; i++)
{
    var currTrack = tracks.Item(i);
    currTrack.UpdateInfoFromFile();
}

run the .js file.
It will "refresh" all information in your itunes library.
