Right click your taskbar at the bottom, click properties.
You should notice a tick box with "hide inactive icons" next to it.
Click that then click 'customise', from there you can control it.
I know this is probably a simple solution, but I haven't been able to figure out how to do it. On the right hand side on the taskbar, you have programs that will start up there when you turn on the computer. How can you delete how many things are there permanetly so they don't come up every time you turn on the computer? I know you can right click them and turn them off each time once the computer is running, but is there a way to delete them so they just don't appear there at all?
