Vista sounds with increased Bit-Rate and louder sound. Better quality! Extract to the media folder in %windir%\Media. Enjoy! . These have been edited with Sony Sound Forge and to give them extra quality and to make them more smooth.
i'm not sure what you mean by manually configure. when i extracted the files i played them back in vlc to compare them to other vista sounds i have.
i've since downladed your files again (i thought maybe something got corrupted) but still in that media part2 folder theres nothing but 0kb files there. media part3 looks to have the same stuff as media part 1. maybe something got messed up when winrar split them up?
also, i still cant find the proper vista startup sound. in your first folder you do have one labled "Windows Startup" which might have been it.. except its not. its just a *blip* sound..
