New Dell XPS 15 running Windows 10.  I've had this computer for 4 days and I get a notification from Dell Update that the system has been updated every time I restart the system.  When I go into Dell Update, it indicates that the last update was 3 days ago.  

1.  Is it normal that I get this notification upon every system restart?  Does it actually mean that the system is up-to-date?

2.  While Dell Update software does show what updates have been done to the system and the version number, it doesn't get any more info, e.g. data/time that update was applied, or summary notes of the update.
