Does anyone know exactly where I can find the .wav files for the old default windows startup sounds?

Which version of windows?

I want the ones for 98, ME, and 2000. Especially 98. Just the defaults though

Sorry mate, been googling for you and have come up empty.

Yea I googled all day but haven't tried limwire or frostwire. Would you happen to have any of those old OS's on Virtual PC? If you have an old installation CD, that would rule
