You can have your computer play a sound when certain events happen, such as when you log on or when you receive a new e‑mail. Windows comes with several sound schemes that play for common program events. Additionally, some desktop themes have their own sound schemes.
Open Audio Devices and Sound Themes by clicking the Start button , clicking Control Panel, clicking Hardware and Sound, and then clicking Sound.
Click the Sounds tab, and then, under Sound Scheme, select the sound scheme you want to use.
Click the Sounds tab, and then, in the Program list, select the event whose sound you want to change.
Under Sounds, click the sound that you want to associate with the event. If the sound you want to use isn't listed, click Browse to locate it.
To preview any sound in the Sounds list, press the Play button.
If you make changes to the individual sounds in a sound scheme, you can save the changes by saving a new sound scheme.
Click the Sounds tab, and then, in the Program list, assign the sound you want to play for each event.
Under Sound scheme, click Save As, and then type a name for the new sound scheme.
