The Steam icon is there on the Screenshot you posted -- Bottom right side of screen in the icon tray next to your wireless connection icon and the PC issues flag icon !
no but im wondering about the icon on the left near the start menu
You unpinned it from the taskbar. Find the program in your steam folder (steam.exe), right-click on it and pin it to the task bar.
If it's already running, running, right-click the program's button and then click Pin this program to taskbar.
that's what ive done and it hasn't fixed the problem. this "file" icon appears. however i just tried it again and it worked. maybe i thought i was doing it right but i guess not. thanks for the help everyone
