Some of my computers have two startup entries for dropbox. If you open Task Manager - Startup, there are two things using PC resources at startup. The first one appears as "Dropbox (3)." That is the one I am used to seeing, which should run at Startup. But the other is "Dropbox Update (4)." Why is this second thing in my PC startup? I have the same Dropbox installed on several computers. None of the desktop computers have this "Dropbox Update" running in the computer startup processes. But all three of my laptop computers have both Dropbox entries running at startup. Why? I would like to eliminate unnecessary startup processes to help computer performance. Why would laptops have this extra startup for Dropbox Update?
