Clean Install Windows 10 Pro ver. 1809
I have a question to ask before I go further to have clean install on my desktop. Yes I know that I should have a full back up copy of the main drive but what program will do to get all the files together something like Norton Ghost or other program. My question is that after the clean install of Windows 10 Pro do I have to activate the serial number or have to purchase one or already there in my previous version. So I can go over to Settings > System > About and see my Product ID for my desktop. Is that the one I should write down before go ahead to do clean install of Windows 10 Pro. Yes I do have the DVD disk of Windows 10 ver. 1809 from download.
Your help would be appreciated about this.
