Installation and Usage question(s) for Windows 11

Greetings!

I have a couple questions about the installation and usage of this software on a Win11 machine.

1. Installation docs I was following along with simply stated I download the software package (no link or winget snippet), but not how to install/activate it. So how would I go about doing this? Normally I'd do a winget, but unless I'm doing it wrong, it can't find ffmpeg.

2. When running the command from "C:\myuser\example>", what would the correct command be to remove all metadata from mkv/mp4 files in their respective folders on a remote source on the network? "\\my.media.server.ip\movies\" and then search IMDB/TMDB/etc.... and re-build the metadata tags, I would be perfectly okay if it had to seek out the information using the file name, as I figure that's part of how Jellyfin is seeking info.

I figured I'd ask here, as the reddit thread I was reading is archived and almost 10 months old. Was indicated by the OP that ffmpeg was having issues running the command over the network, as it sometimes ended up stripping the video/audio from the file along with the metadata.
