If it always comes back after reboot & start up, here's some things to check.


Find the settings/options /preferences in the MS Word toolbar.
I'm not sure what name they use for the settings area - but possibly in the general settings tab there should be something about "start up -" when windows starts" or something along those lines.
If you see that un check the box.

I don't have MS Word on my computer, so I can't look on mine to make sure exactly where or what the wording might be.. maybe someone else has it and can check on their machine.
I'll look for a link about it and post if I find it.


Also check your "Start" & then Programs - under Start Up - see if anything is listed to start there.
