The exe is clean and it's English, but you can use the 2024 versions of yt-dlp by using --allow-u to download drm protected videos

You will need ffmpeg installed, and I did write it for Linux, so I'm not sure if there are differences for windows. Worst case you need to slightly modify it to work on windows.

If you guys can recommend a fair and open pastebin alternative for me I will upload it there as well and edit this with the link
