This is a simple bat file that will turn all NPCs in the main game (i.e no Dragonborn or Dawnguard npcs) non essential, regardless whether they offer quests or not.

I like to finish all my Skyrim runs with a nice kill everyone, but that is in Oldrim. In Special Edition, I haven't found a mod that reliably turns all NPCs non essential so that I can kill them without having to manually set each one as non essential in the console. So, I looked up a list of all base IDs and through the magic of Microsoft Excel I added a setessential [NPC BASE ID] 0 to all NPCs. To use : Extract the file into the main Skyrim directory, start up Skyrim then hit the console key (`). Type in the following : "bat allnonessential", then hit enter. If you have no error messages in the console, then it worked. Note : you can change the file name, in which case replace "bat allnonessential" with "bat [your file name].
