You'd like to think that in 2021 installing a font would involve just copying it and some advanced AI system would notice it and install it on Windows. Again the future has failed us.
Let's say you have a folder of TTF fonts you need installing. Just copying them to the
c:\windows\fonts directory won't work. You need to copy them with a magic COM command that is probably left over from when file names in Windows looked like
PROGRA~1. I've seen some scripts which add the font to the windows registry but I didn't have much luck getting them to work and they feel fragile should Microsoft ever update font handling (ha!).
Here is a script that will copy over all the fonts in the current directory.
echo "Install fonts"
The fonts don't seem to get installed using the same file name as they arrive with so that last
cp line puts the original files in the fonts directory so you can run this script multiple times and it will just install the new fonts. If you wanted to get cool you could check for a checksum and install fonts where the checksum doesn't match. Don't both trying to use
CopyHere with the flag

If you want to check and see which fonts are visible to .NET on the system then you can try
