By default Second Copy starts when you login on Windows. While it is idle in the background, you will see an icon for Second Copy in the System Tray. If you do not see the icon, Second Copy may not be started. In this case, run Second Copy from the Start menu.

Note:
If you want to open the main Second Copy window automatically when it is started, uncheck the box "Start minimized" from the Edit | Options | Startup tab.
