You also have a lot of other things to shut down such as any updates since many of those will almost every week update and maybe call for a reboot which can cause that screen.
Why not try a boot of say Ubuntu and VLC Player if you must do this. It's a little more under your control.
How do you stop the screen that says user 2 programs running from coming on?? I am running media player 11 and want it to run continuously however this annoying screen always comes on. I've removed java from the computer (don't need it) and changed the startup with MSCONFIG. Nothing works, I'm ready to toss the computer. I need the media player to run without interruption! HELP!!!
