Simple, Easy, and Free: Black background for OneNote 2010, OneNote 2013, and OneNote 2016 (no junkware/spyware)

If you'd like a black background for OneNote, you can buy OneNote Gem (which is fantastic), or you can download a free OneNote 2010/2013 formatted section whose background is already black. You just double-click the file, OneNote will load, and open a new section whose only content is a new page with a black background. Yay!
