Folks, what is difference between these 2 options available under:

Update >> Advanced Options >> Choose how updates are delivered

Get updates from Microsoft, and get updates from and send updates to:

1. PCs on my local network
   
2. PCs on my network, and PCs on the Internet
   

More specifically, which are PCs on the Internet that I am updating?

It helps making faster updates when in home / office there are more pcs with windows 10. First pc uploading shares updates files to other pc in same network. Leave enabled
The 2nd option instead bring you updated files from opther pcs ON THE WEB too. Better to disable it ;)
