Newest STS is extract only? no installation?

I've noticed the new STS is extract only and nothing is installed unlike the previous versions.

Question: 1. I want to run Maven in the cmd. Can I use what STS is using? If yes, where is it so I could add it in my env vars. If I can't use it, so it means I need to install maven separately although STS already has one?

Can anyone clarify this matter? Thanks.
