When i start my pc, steam starts running on the background, so i´m always online on Steam, weird thing is that i can´t disable it, i see the option and i click that i don´t want Steam to open when i start my pc bla bla and nothing.

Explains the numbers they have of Concurrent users, argh. 

Sure you can, at least on Windows. What OS are you running? I usually disable Steam on start.

Just did it, had to reboot my pc, it was a bug with Steam or my Pc i did it like 5 times and Steam always opened, now i just rebooted it and it worked lol

i hate apps that open automatically god damn it.

i like seeing Steam numbers, i just hate that was opening on my pc without i want, i use Steam but dont want it always open showing friends going online and messages etc etc...

I do it through Windows.  I like to keep my start programs low.
