Name and in parentheses will change to (new computer name) after restarting this computer.
I changed the computer name, rebooted and it still has the out of box computer name when you right click This PC in Explorer and go to properties and look in the Computer name, domain and workgroup section.
I have a new PC (out of the box) that has Windows 10 Pro and in setting it up, it upgraded to version 1703 (OS Build 15063.540) when I checked for Updates.
