First, typing in all capital letters is considered shouting and rude.
Second, go to Start>Run and type "msconfig" without the quotes. Look
in there for something that resembles the "HP-Info Window" (since you
don't give specifics, I can't say whether what is starting is
necessary for your HP device) and uncheck the box. Click Apply and OK
and it should not start any more. If you need more help, post back
with better details of the problem.
