On Windows, Spike is started and stopped using the "Start Spike" and "Stop Spike" menu items in the Start Menu. This will also create a project directory named "spike" in your home directory (c:\Users\<USERNAME>), and it will enable/disable the system-wide proxy settings. Select "Start Spike" under Start Menu > Spike, and then go to http://localhost:9600 to see Spike UI running.

Command line options
