The original sound scheme is preserved with its original Windows-10 name. For example, if the current scheme is Sonata, and you change one or more sounds, the new scheme is called Sonata (modified). When you change one or more event sounds in Windows-10, a new sound scheme is automatically created, and is given the same name as the current scheme, but with '(modified)' added. Additionally, some desktop themes have their own sound schemes.

(An event can be an action that you perform, such as logging on to your Windows-10 computer, or an action that your computer performs, such as alerting you when you receive new e‑mail.) Windows comes with several sound schemes (a collection of related sounds) for common events. You can have your Windows-10 computer play a sound when certain events occur on your computer.
