To make the program start up just on taskbar right click the TT rgb icon on the taskbar and you will see a option that says "Run TT RGB Plus Program when Windows starts"
It has a box next to it. If the box is solid it like below it will open on your desktop at startup
If the box is hollow like below it will start on the taskbar.
yes it is bad wording should say something like "start in background" or "start hidden"
