I have looked everywhere for this... YouTube, Google, and even some threads in this forum, but none of it worked and it still plays the "so-default Windows 7 boot up jingle". I really want to change the boot sound into a Windows XP one just because I like it, and like I said, nothing seems to work, I tried from modifying registries to replacing wav files on WinSxS. Can anyone help me? Thanks in advance!
