When I got Windows 7 I disabled all the annoying sounds on it. When I minimize a program, delete something, etc. The most annoying of all is the internet ones. I frequently disconnect and reconnect with my internet cause my laptop sucks. It's some model our school bought and everyone in my year has retarded problems with the internet. It's not the OS, it's not the network, it's the way our computers are built. But anyway the internet sounds were these low buzzing sounds that played over my music and I noticed it happened at the same time as the d/c'ing so I knew it had to it. But now the sounds still continue even though I have all sounds supposedly disabled.
