Windows 10: Rotate a video (Windows Movie Maker used to enable this) and save resulting file

I am on windows 10, and have a need for a program that will allow me to rotate a video (say from landscape to portrait), and save the corrected version. Windows Movie Maker used to have this facility, but WMM has been withdrawn.


I have tried using VLC Media Player: it rotates the view OK, but I cannot find a way to save the amended image to file that can be viewed by anything other than VLC.

Windows Movie Maker substitute

I use Windows 10. There is no topic for my question. If I'm in the wrong place, please suggest the appropriate topic. A couple days ago, Windows Live Movie Maker worked. Today it doesn't, so I updated to Movie Maker 12. It doesn't work either. When
I save a video I've made (sometimes all I've done is rotated right), the saved video won't work right. Says not a correct file type or codec. Am I doing anything wrong? Or should I get a different movie maker for Windows 10? Can you suggest a couple good
free ones? I heard the VLC was good, but it only plays videos. I want a video editor and movie maker like the old Windows movie maker. Thank you.

So what to do ?

And it's absolutely correct - there is no video in that file because it isn't a movie. It's a .wlmp Windows Live Movie Maker Project file, nothing more than a list of the source videos, the edit points and the transition effects saved in xml format.
