I've had the Dell Update program for a while now and still don't know what it does... well, I know it's supposed to update drivers apparently, and it says it checks every few days, but exactly which things does it update? Is it ALL drivers on my system, or just certain ones? How important is Dell Update?

I'm also curious if I even need this Dell Update program now that I have upgraded to Windows 10? I keep hearing that Windows 10 automatic updates does all the work?

I'm kind of an amateur...

Thanks in advance!
