I installed the update on both my laptop and PC, took an hour to install on each computer. It reminded me of when I first installed Windows 10 from scratch didnt know it was going to be that kind of upgrade so I was worried I would lose everything but everything is still here..the look is the same except now you see “I’m Cortana Ask me Anything” and whenever Im away from the computer I notice this little icon that pops up near the clock that says “Location set to on” it looks like a little target symbol not sure what that is about
I think that's letting you know that Win10 is broadcasting your current location (actually, your computer's location) back to Microsoft central for processing. It helps fine-tune answers to questions you might ask Cortana or other services, such as "where can I get a pizza at 3:00 AM?" -- it'll pick a pizza place near where it thinks you are.
