Opus always opens when i switch on computer

Hi new to the forum need an answer to a couple of quick questions,

I close my computer as normal but each time i open it opus loads up with about six windows on the taskbar each one has a different colour opus symbol red yellow and grey could someone tell me why it does this. I have checked the startup on windows nothing in there, read the help files cant find it.
