I'd recommend Microsoft's ClipChamp; it's a free download for Windows 10 users and is often bundled with Windows 11. It's web-based, meaning you need an Internet connection to use it, but it's definitely more feature-packed than Windows Movie Maker. At times it's akin to the current iMovie, but you can work with more than two video tracks, and you get some nice image correction tools, a good title utility and a nice library of customizable video effects. BUT, unlike iMovie, the free version only exports up to 1080p, and you can't do "rubberband"-style audio volume edits the way you can on iMovie.
