If you go that far, metapad (from 98) is still better than notepad ever was. Also loads 100k lines files quickly.

There's still old tiny Metapad. And also more modern and fully featured (but still light) Notepad 2/3/4 and Notepad++. For full replacement, i just renamed all instances to notepad.exe.bak, back then on Windows 7 & 10, and rename-replaced it with metapad.exe. Though, i guess with UWP apps (modern Notepad is one), it's just file associations nowadays. There's surely some mass-reassociate utility around?

Btw, nano is only 50/50 chance that's it's pre-installed. Learn some vim, will ya? ;)
