When a new user profile is created, it defaults to the Windows Sound Scheme.

In a business environment, it may be beneficial to configure some computers to default to be silent.

Using REG.EXE, built into Windows XP, Windows Server 2003, and later operating systems, or installed from the Windows 2000 Support Tools, the following command will cause new user profiles on a computer to use the 'No Sounds' sound scheme:

REG ADD HKU\.DEFAULT\AppEvents\Schemes /VE /T REG_SZ /F /D ".NONE"
