SoundOff 1.0 (Windows)
Source: SD Software
SoundOff is especially handy when you want to listen to music without hearing all the clinks and clunks of Windows actions. To currently do this, you have to go to the control panel, select the Sounds and Multimedia applet, select the Sounds tab, then change to No Sounds. In addition, this program lets you rename and delete your added sounds schemes. It also has an option to make sure your current sound scheme stays that way, as some other programs will change your sound scheme without you knowing.
