I think in this case, you experience a Windows feature which we use in Bome Network now: when restarting the computer, Windows will restart such programs that were running when shutting down, even if they’re not in the Startup group.
To verify: make sure that Bome Network is not in any Startup group (SysInternals’ Autoruns is a more complete way to make sure), then exit Bome Network, then reboot the computer. Bome Network should not be started.
If you had multiple ways of starting Bome Network at startup, then the first one will launch it, and it will display in your preferred way (minimized). But when starting it a second time, it will show its window. We had added that feature because some users couldn’t find the program (it was “hidden” in the tray), and therefore tried to start it again. But then it would only stay in the tray, and the user thought that the program does not work…
