Have you ever heard of a hidden music track in Windows XP? Unbelievable as it may seem, there is actually a 5:25 minutes track named Title.wma in every Windows XP installation, in the C:\WINDOWS\system32\oobe\images folder. It is actually played everytime Windows is installed or activated successfully. But if you still have installed or activated Windows 100 times, you might not have heard it, because at that time, you did not probably have your soundcard drivers installed.
Note : You need to select “Show hidden files and folders” and uncheck “Hide protected operating system files(recommended)” to view the “C:\WINDOWS\system32\oobe\images” folder.
