I just installed Vista Ultimate on my computer. I am wondering if any one here has experience with it? mainly i am curious how to turn off the little pop up that lets me know the computer is about to do what i told it to do.

for instance i click on mozilla to get on the internet (i don't use IE) and a box comes up to let me know i am about to open mozilla. its not a big deal but its annoying and it does it with a few other programs. is there a way to make it stop?
