I gave up on MS when Windows 98 became obsolete, and upgrading would mean a new computer. Since then I have exclusively used Linux, currently Linux int 22.1. For word processing I use Libre Office*. It produces (if you want it) a Word compatible (sort of) output that for me has not raised any eyebrows from my correspondents, including editors.
*Libre Office is available for Windows and MacOS as well as Linux.
