Windows XP has a hidden sound track which plays as background music during Windows XP installation process, but most people can’t hear this music because they have a sound card that does not have drivers preinstalled on XP .
There are 2 ways by which you can find this hidden sound track:
1.Go to start->search.Search for title.wma .But remember to include hidden files and folders in your search.

2.Navigate to C:\Windows\system32\oobe\images, go to Tools > Folder Options > View, check Show Hidden Files and Folders options and then uncheck Hide Protected Operating System Files. You will now notice a file called title.wma, that is the hidden sound track.
