The Hidden Microsoft Song

Do you know the hidden Microsoft song? I hear this song while im installing windows, where its almost at the end where have to register your windows, enter your username.......etc. 
Some people might not hear it because, your sound card driver isn't installed. If you want to know and hear that song, here it: 
Go to Start > Run > Copy and then Paste, or press and hold theStart + r .

C:\windows\system32\oobe\images\title.wma

and hit Enter, of course ... Your media player should load the song, and now you can hear it.
