I tried following this FAQ · neovim/neovim Wiki · GitHub but did not work
upon reading the original stackoverflow post that mentions this neovim wiki page, there is a comment that mentions if you install other clip things then it will override it or something.
" you should specifically configure
neovim to use
win32yank.exe . The issue being that if you have now (or later install) any of the other options with a higher priority (
xclip , etc.) then they will take precedence and your clipboard will not work/stop working."
