Beep.Exe for Windows

Beep is a tiny command line utility for Windows computers that uses the internal PC speaker to make a notification sound. This can be useful in situations when you do not have a sound card or speakers are not connected or turned on. Freeware.

Typical usage is in batch scripts or similar to signal events. For example, I use it myself to signal when my PC has booted and launched all startup applications and is ready to use.
