So This Is Not A Question Just Let you know.

You Can Still Download Windows Movie Maker In 10 (or more)

But you need third party sites to download it because you did not have Windows Essentials 2012 (or you have).

I recommended topwin (https://www.topwin-movie-maker.com/download.aspx)

there's Windows Movie Maker 2021 not by Microsoft download The Windows Movie Maker Classic
