I have Windows 10 with OneNote pre-installed, but it's a very lightweight version of the real OneNote 2016.
How can I install OneNote 2016? If I go to www.onenote.com to install the full version, it says that OneNote was already shipped with Windows 10.
I have read that there is a difference between OneNote and OneNote 2016 (and 2010, 2013, etc.), and in the lightweight version, it seems I cannot insert equations, customize the layout, etc.
