Wow, what a coincidence. I should've poked my head in here as I had to do some last minute video editing last week.
Video Editor Master (From the Microsoft app store) seems like it should do what you need. But I couldn't use it because it supports all formats except MOV.
HD Video Converter Factory Pro is decent, but the free version only allows 5 minute video clips.
Filmora was a very advanced editing program, people have made movies with it. The free version only supports up to 720p videos, however.
Sadly [MS Movie Maker] reached End of Support in January. It's not offered for download any longer.
Come on now. This is the internet we're talking about. You absolutely can still download it.
I thought so as well... but NOPE. You can't because it is part of the Windows Live Essentials installation package. You can download the WLE installer, but it then tries to access a MS server to download the latest catalog files. And as those are removed the WLE installer no longer can find anything to install.
