1. Edit the plugin_customization.ini file in Notes : at c:\Program Files\lotus\notes\framework\rcp\plugin_customization.ini or c:\notes\framework\rcp\plugin_customization.iniI actually found my plugin_customization.ini file at c:\Program Files (x86)\IBM\Notes\framework\rcp\ but it's expected that there's some varying between systems (naturally). Anyway, following these steps worked like a charm for me, so it should for you too, making your system tray just a little bit cleaner.
2. Add the following line: com.ibm.collaboration.realtime.application/useSystemTray=false
Once this is done, close Notes and launch it again. This should work.
