I run Norton Security with Backup (10 subscriptions) on a number of different Windows 10 systems, some of which have been upgraded from older versions (e.g. WIndows 8.1, etc). How do I now verify the name in the Norton web site inventory and match it now with the Norton application running on the client? For example, I if I had three 8.1 clients named A, B and C and deleted one of them how will I now know which of the 2 remaining systems (now upgraded to W10) match with A, B or C on the Norton web site?
