No, I don't see the point. SSD's and even newer mechanical drives boot up Windows pretty darn quick, especially on Windows 10. Leaving it on all the time not only consumes more electricity but also will reduce the lifespan of your components, although usually this is fairly neglibible. Fans are the main thing I think of going bad due to being on all the time. Also Windows 10 in particular, but older Windows versions too, rely on shut downs and restarts to perform updates. I shut my computer off pretty much whenever I leave my room for more than 15ish minutes.
