By default, Window 10 automatic updates. These days window use pear-to-pear connection for update in order to save bandwidth and you can disable pear-to-pear updates in setting.
To see what processes are running, open Task Manager (ctrl-alt-delete). Another program to try is SysInternals process explorer.
I have Win 7. I find there are so many processes running, that it's difficult to know which ones slow down performance. If you watch long enough, then you might notice when a program opens and closes, or when it hogs ram, or cpu activity, or disk activity, etc.
