IMHO you can't go wrong with Sony Vegas Movie Studio. It has everything you need at a reasonable price. You don't need the very latest version, you could pick up an older version cheaper and it would still do everything you need.
It's not what I use (only because I had already purchased an inferior editor that works well enough to keep using for now) but if I could go back and do it over I'd pick up Sony Vegas instead.
Windows Movie Maker gets the job done too, it's free but they stopped supporting it in 2014 so a little clunky/out of date.
For reference I use Wondershare Filmora (aka Final Cut Pro for Windows) to edit. As I said, it's serviceable but not great and costs the same as Sony Vegas, so why not just get Vegas instead.
