how do you find Windows language settings via Everything?

Use Wox https://github.com/Wox-launcher/Wox It launches any tool and if it doesn't understand, it starts searching all files using Everything

Huge, longtime lover and advocate of Everything here - it's just so powerful to be able to find every file Everything knows about with .jpg in the name, sort by date, then if I really care start filtering by drive and folder ("C:/Users/[name]/Downloads"). Having folders sorted into a sane hierarchy is important, but being able to open Everything with Ctrl + Space (my preferred shortcut on a computer that I won't also be gaming on) and start typing is great and usually so much faster.

Also works pretty well with mapped/mounted drives - sometimes there are issues, but I suspect most of those are Windows/network based, not Everything's fault.

I use Keypirinha's Everything plugin to access Everything within the launcher. The upside is that your queries are saved in history. You can scroll to that query in history and make the search again or edit that query.
