I have the wireless 8000 keyboard & mouse combo the program come with when i install it. It show two icon in my system tray but when i let computer idel the hotkey setup icon in system tray goes away and i can adjust volume no more with my keyboard i dont know if driver need to be updated i never updated it but where do i go to do so link please.

Are you concerned because the icons for mouse and keyboard aren't showing in the Notification area. Don't be. IF it bother you:
Right click on Notification area> Properties> /check 'Hide inactive icons'> click on Customize> find the icons you want> change dialog bot 'always show'> Clock.

A NOTE:: these icons have a reputation of not keeping the settings. Just ignore that- reset if it bothers you.
