It really depends on which processes you shut down and what program they are associated with. Were they generic Windows processes? If so then what you may be noticing is NEW processes that have been called by Windows programs. If on the other hand you are seeing processes that are from some other 3rd party software, then any time you re-start that program it will re-start those same processes again. If you could post a list of the process names that you noticed running, maybe one of the more experienced moderators or Admins could advise you on this.
