I've just removed Norton using Win10's Control Panel (followed by using the Norton Removal Tool) before reinstalling it.
During the process up popped a Norton Technical article per the attached text file. I didn't take the web page at the time and despite an intensive search via Norton, I've not found it since.
Anyone removing/reinstalling needs to print out such instructions. Instead of us having a messy copy & paste could we have a 'Print' button?
Also, anyone using the Norton Identity Safe Vault will probably have forgotten their Norton Account log-in ID & password, that they'll need to reinstall NIS later, when they won't yet have the Vault. A reminder to make a note of your ID/password would be very helpful!
