Use netinstall to re-install the OS and wipe the configuration. Alternatively, depending on hardware, use the reset button to clear the configuration.
Both methods are outlined on the wiki.

Un-plug drive (or remove CF card, or whatever medium you installed RouterOS on), connect to Windows machine, use netinstall to re-install OS and wipe configuration.
